Quiz Friday 10th, random integrals...
Presentations: Joseph L. 225, Ryan 226, Zach 227, Andrea 228, Cody 229.1, AJ 229.2, Juan 229.3
A couple of things I keep forgetting to mention in class. (1) You get credit for "good" questions in class -- if you don't understand something, find a way to ask a nice question like "I just don't understand how you started this problem, how did you decide on the first step?" Asking the right questions in life is very important. (2) There are practice problems (with answers) for each chapter. Look at the table of contents to find them. (3) There are appendices with all the trig identities, area formulas, derivative rules, etc. Again, look at the table of contents!
Lecture: Trigonometric integrals!

This was a good day -- many good presentations -- keep up the good work and we'll all get good grades!
I'll answer Andrea's question and make comments on the point of problem 212 at the beginning of next class.
I'll also talk about how we tackle rational functions and how we break up the rational functions when we
use partial fractions.
Don't forget to friend Calculus2414 and ask questions there any time!

Welcome to my Calculus II blog. We also have a facebook group, Calculus2414. If you request to join it,
I'll let you in. Don't worry, we don't have to be facebook "friends" in order to both be members of the
group. What you post there will only be visible to our class.
Begin by reading the syllabus (see link above) and the notes (see link above).
I strongly recommend that you meet and speak with someone who has taken a course from me before. While
you will find my teaching style very non-standard, I think you will find that people who have had me before
will say that I am hard, fair, honest, and that I expect a lot from my students and in return am willing
to give a lot to my students. But I could be wrong, so ask them.
Everying below this line is the blog from last semester -- you can read it if you want just to see what
happened last semester, but you don't need to.
Presentations:
Problems to understand/present before the exam: 182, 186, 187, 188, 190, 191, 192, 212, 213
Exam is this Friday at from 11am to 1:30pm.
I have a rough draft of your grades. You may stop by anytime. I encourage you to look at
the number of presentations I have recorded and be sure that I have not missed any. Of course,
I list them all on the website, so you can check there to see how many you have and compare
it to the number I have recorded in my grade book.
The exam will consist of no more than 20 straight forward questions. Examples:
Graph f(x) = x^4-x^2 and list the inflection points.
Compute the derivative of: (a) f(x) = cos(x^3) (b) z(x) = x^2*sin^{-1}(x)
Compute the Lower Riemann sum of f(x)=x^2+3 over the partition {0,1,3/2,2}
Simple word problem -- i.e. just like one we did in class or on test!
Presentations: Johnny 182.1, Ismael 182.3, Scorpio 186, Austin 187.1,2, Jessie 187.3,4, Travis 188
Problems to understand/present before the exam: 182, 186, 187, 188, 190, 191, 192, 212, 213
Basically that gives you new stuff of: Riemann sums, area under curves, definite integrals,
area between two curves, and u-substitution.
I have a rough draft of your grades. You may stop by anytime. I encourage you to look at
the number of presentations I have recorded and be sure that I have not missed any. Of course,
I list them all on the website, so you can check there to see how many you have and compare
it to the number I have recorded in my grade book.
Remember, the exam is one week from Friday -- two days after our last class. The exam will
consist of no more than 20 straight forward questions. Examples:
Graph f(x) = x^4-x^2 and list the inflection points.
Compute the derivative of: (a) f(x) = cos(x^3) (b) z(x) = x^2*sin^{-1}(x)
Compute the Lower Riemann sum of f(x)=x^2+3 over the partition {0,1,3/2,2}

Test!
Monday I'll introduce you to Riemann Sums (section 4.2 -- read ahead!) and return the tests.
I tried hard to make all the problems doable, but given how long everyone took, I'm worried!
Problem session today 2:40-3:30, L113.
If you FB or email me, I'll be checking a minimum of 2-3 times a day, so should be
able to get you quick answers back.
Presentations: Ted L'hoptal's rule, related rates, max/mins,....
I can't do a problem session on Monday evening -- guests arriving.

Lecture -- integration and word problems.
I know these word problems challenge you! Any one you want to see re-worked after you
study them, I'll happily put on the board. I'll copy a few more from a calculus book also.
Coming soon! Test on Wednesday before Thanksgiving over infinite limits, graphing,
word problems and integration!

Presentations: Corey 147.1, Juan 147.2,.3, Andrea 148.?, Jesse 148.?, Joshua 152 (Kira photo'ed it
and it's on FB Calculus2413 page if you need to see it.)
Monday -- more problems from you, but I will also give a lecture at the beginning over Max/Min Problems,
the section after L'Hopital. It takes some time to get these word problems to sink in, so we
want to start them now to give you a few weeks of thinking about them before the Thanksgiving test.

Presentations:Mark 91, Erica 94, Joshua 96, Kira 97, Weslynn 98,
I deleted the "Bad" Calculus2413 page, so now if you go to facebook and search for "Calculus2413" you
WILL find the NEW, CORRECT facebook page. (If two still show up for some reason choose the GROUP
not the EDUCATION one.) I know I really flubbed starting this page, so I'll
give you ONE presentation grade for going and requesting to be added to the group. If you
are morally or poltically opposed to FB, instead of joining our group, you can find a
good Calculus help site and email me that link for your presentation credit.
Presentations: Jesse 78, Cesar 84, Rachel 85, Juan 86, Andrea 87, Shaina 88, Ismael 89, Cody 95

Big Picture Lecture: derivatives, higher order derivatives, graphing via derivatives, derivative rules, and differentiability
See you Monday for the "big picture" lecture.
Presentation: Tyler 57, Cesar 59, Mark 61
Ways to improve your grade. (1) Explain your presentations at teh board. (2) Ask me for a
"big picture" lecture occassionally -- one coming Monday. (3) Spend 2 hours on the course
every night. (4) Work on and ask about the practice problems in 15.1 and 15.2.
Presentation: Johnny 50.1,3 (thanks for remembering), Cory 54, Chris 56, Kira 58
Next time: 57, 59, 60,...
I'm open to suggestions to help you improve your understanding. The suggestisons I can make are:
1. Every day review what we did in class and if you have a question about any problem, I'll
rework it at at the beginning of next class. 2. Try multiple problems every night and if you
don't get at least one or two, come see me or the math lab. 3. Work your homework in the math
tutor lab upstairs in Lucas where you can get help any time. I walk by all the time and check
on my students, but there haven't been any in there this semester from this class!!!!! 4. Start
the practice in 15.1 and if you can't do one, ask me in class to help. 5. ASK QUESTIONS IN CLASS.
All that matters is that you understand. If we don't cover all the problems, I'll address them
the next day -- the only thing I care about in class is that you understand or ask questions.
Presentation: Cory 49.5, Andrea 50.2, Johnny 50.1,3 (put on board again tomorrow), Trais 51, Jessie 52, Weslynn 55.1,2
Come talk to me about your tests if you are concerned. I give great pep-talks! Seriously, there is no one in the class who can't survive calculus *if* they have three things: the time, the will, and the persistence. Stay with it. Now quit reading my blog and get back to the problems in Chatper 2!
Presentations: Jimmy 49.1, Cody 49.2, Jessie 49.3, Travis/Eli 49.4
Test!
Good luck on the test tomorrow!
Presentations: Zach 25.1, Austin 43, Killogh 48
Test: September 15. The tests will be on my desk before class starts. You can start 5 minutes
early and leave 5 minutes late to give you extra time. If you have a note from Office of
Disabilities, you need to get it to me now if you need more time than the extra 10 minutes I'm
offering now.
Thanks Andrea and Zach for asking me about the presentations -- I do forget sometimes. But Friday I just
ran out of time and felt horrible and went home without my grade sheet!
Presentations: Monty 42, Austin 43 (please put up again tomorrow...), Tina 46, Kira 47, Tyler 45

Jessie -- be sure to ask me about the number of questions on the test in class! As a rule,
I try to make about 40-50 points worth, with each problem worth 4 points, but sometimes a
problem has two parts, each worth 4 points.
Eli -- I failed to go over your problem (32). Please put it up frist thing tomorrow.

If you want to check out some youtube or kahnacademy.com videos on the "Squeeze Theorem", now
would be a good time. I thought I would talk about it today, but it was important to make
the derivative connection make sense, so almost surely I'll address the squeeze theorem tomorrow
along with a bit of trig. Buzz words: Unit Circle, Graph of Sine, Squeeze Theorem.
Presentations: Eli 24.1, Hayley 24.2, Audrey 26, Kira 28
Remember to check that your presentations are listed here when you present! This is your
way to be SURE you get the credit you deserve. You did a lot of presentations and doing this
will get us ahead and allow me to give some extra lectures where needed (trig!, e^x, ln(x))
later in the course. So, keep up the good work and it will benefit all your grades.
Remember, it's called Labor day because you are supposed to Labor over Calculus all weekend. ;>
Presentations: Cesar M. 21.3, Scorpio 21.4, Kyle 21.5, Chris Collins 21.6, Juan CC 22.1, Stanley 22.2, Chris R. 22.3, Joshua 23.1, Shaina 23.2, Andrea Wion 23.3
Help! I did not write down who did 19.1, 19.2, 19.3 when I took over from Brandy this morning!
Email, text, or post on Calculus2413 page if you did these so I can give you credit.
Presentations: ??? 19.1, Scorpio 19.2, 19.3, Kyle 20.1, Hayley 20.2, Tina 20.3, Chelsea 21.1, Zach 21.2
I'm happy to see any problems up through number 24 tomorrow. Some limits, some graphing,
some continuity. Someone pointed out that kahnacademy.org has come great videos! Please
post on the facebook page (Calculus2413) when you find good resources so everyone can use them.
Also Chapter 15.1 has practice for Chapter 1 and the answers are there also, so you can
start doing your practice work. In class we learn and discover ideas. At home you
practice these so you'll do well on the test, coming up Thursday 15th.
Presentations: Weslynn 15, Scorpio 17.1, Tyler 17.2, Cory 17.4, Zach 17.5, Andrea 17.6, Chelsea 17.7
Good start on limits. Read about continuity. Someone pointed out that kahnacademy.org has come great videos!
Presentations: Ismael 13, Erica 14, Mark 16.1, Eli 16.2, Killough 16.3
The purpose of the facebook page Calculus2413 is so you can throw out a question any time, day or night,
and maybe I'll see it and maybe I won't. Either way, maybe someone else will and will help you! If
I see someone helping out a lot, I'll help them out at the end of the semester. I would like us
to become a community of learners, not a bunch of lost students struggling by themselves!
As a class, you are off to a good start with 15 problems done the first week. I encourage you to
email or text me if you have questions about how the class is run, how I grade, anything. Or
drop by my office any time. You don't have to wait for office hours -- I'm usually here from
7:30 am - 3 pm except when I'm in my other class which is 9-10.
Kira asked me how many questions one needed to present to get a good grade. I meant to
answer that question in class today, but I forgot, so will answer it on Monday. Someone
remind me if I forget!

Don't forget you need to turn in one problem on Friday. Choose a problem that has already been
presented or, if you prefer, one that has not yet been presented. Don't go past problem 20.
Write the problem statement at the top of the page, then write the solution out very carefully so that even someone who
did not understand it could follow your explanation. Turn it in at the beginning of class
Friday.
Friday's Class: Collect homework, then T1 [ graph y=(x-1)/(x^2+3x) ], 8, 9, 10, ... as far as we can get.
Presentations: P1 Hayley, P4.2 Scorpio, 4.3 Kyle Payne,4.4 Zach Knau, 5 Chelsea Horn, 6 Lashaina White
Good day -- six problems on the board and mostly correct. I made a (nother) mistake and did not go over Hayley's solution to
P1, so we'll ask her to put it up again tomorrow. Don't let me do that -- jump up and say "Ted,
aren't you going over my problem?????" I just walked right past it by accident. This is YOUR
class and YOUR chance to learn calculus. Take charge! Come to class tomorrow with a solved problem
from the notes or T1 [ graph y=(x-1)/(x^2+3x) ] OR have a question ready to
ask Brandy or me. In this class, we spend our time learning not listening to dull lectures and
then figuring everything out again at home. Ask questions in class!!!! Come by my office!!!
Ask those other burning questions in your mind like, "why do you teach this way" or "what is
math good for" or "how do you keep your slim figure!" ;>
Now, quit texting and watching youtube and fb'ing and get to work.
Presentations: Q1 Kira, Q2 Tyler, P1 Hayley, P2 Cory/Chris, P4.1 Johnny, P3 Rachel.
Welcome to my Calculus blog! Brandy and I will do our best to make Calculus a fun
and enjoyable experience for you.
First, read the syllabus for this class.
Here are the only notes you'll need for this class.
Do NOT print out all the notes! I sometimes modify them and upload a new version.
Just print out a few pages ahead of the class or read them on your Ipad.
Tonight, be sure to read the Introduction to the Students and then start working problems in Chapter 1.
If you can make it through all of 1.1 you are doing great!
Every day will start the same. We'll ask if you have questions. Please ask if you don't understand the
notes, a definition, or a problem that went up yesterday. We'll help. I'm happy to repeat any problem
you did not understand from the previous day. Then, we'll see what you have to show us.
Respect: Keep all your conversations in my room about mathematics and keep your phones hidden with ringers off.
If you read or send texts during my class, I'll throw you out of class.
Presentations: Andrea Wion, Troy (last name?), Cesar (Melendez or Valle?), Kaitlyn Padgett, Chris Collins
Did I miss anyone?
I've already made my mistake at the board! The function should have been h(t)=-16*t^2+100t +5. I wrote
100 instead of 10 so the ball only went up for a fraction of a second. So, the first questions
for next time are: When is the ball at a height of 10 feet? When does the ball hit the ground?
You'll need a calculator and the quadratic formula to solve these.
Almost forgot -- go to Facebook and like Calculus2413 -- that will be our group where we can communicate.
