It should say "if integral from a to infinity g(x)dx converges then so does integral from a to infinity f(x)dx" and "if integral from a to infinity f(x)dx diverges then so does integral from a to infinity g(x)dx."

Note: I drew ln(x) instead of e^x. Don't judge me.
Also, to properly motivate using Taylor Series to approximate, imagine that instead of just trying to estimate e, we were trying to estimate e^x for various x in [0,1]. This is a thing that engineers, scientists, etc. may need to do. Then finding the error once and evaluating the polynomial would be easier than calculating each e^x.

What to Expect
This recitation section will be a mixture of me talking through examples and important points at the board and you doing worksheets with your classmates. Attendance is not required, although you need to come on Tuesdays to turn in homework.

Office Hours
None, due to the Coronavirus Pandemic. Email me to set up a videochat.
My office is Vincent 555. My typical office hours will be as follows, however I will be out of town for several weeks, so please notes the changes below. While I will be cancelling some of my office hours, I have added some to make up for that.

- I will generally respond to emails within 24 hours on weekdays and 48 hours on weekends
- Let me know in advance if you need an exception or extension for homework
- If you want to talk about your class performance and strategies to bring up your grade, we can set up a short meeting
- I do not make appointments to give extra help on the course content
- Work will typically be returned to you one week from when it's turned in
Recitation Grade
Recitation Grade
Each Tuesday, I will collect homework at the beginning of class. This is worth 20% of your course grade. I will grade two problems off of each homework.
There will be 13 homework assignments throughout the semester. I will drop your three lowest scores, so your total recitation grade will be out of 200.
- Scoring
- 5 points for homework completion and timeliness (-1 for each day late)
- 5 points for clarity/organization (including handwriting), thoroughness, and writing (when applicable)
- 5 points per problem graded for correctness of the solution
- Things to note
- Please leave margins so that I have space to make comments
- Please label your problems neatly and clearly so that I can find each problem easily. Best practice is to label them in the margin on the left and don't put any work in the margin
- Please do HW problems in order, or make a note if they are out of order
- If I can't find a problem, I will assume you didn't do it
- Make sure your name and section number is on your assignment
- Make a note on your assignment if you work together or use resources other than the textbook. Working together is encouraged!
- STAPLE YOUR WORK BEFORE YOU GET TO CLASS
- If you don't have a stapler, you can run up to the math library on the third floor and use theirs
- A paperclip is not a staple
- I will take off one point if your work is not stapled
Expectations for written work
Expectations for written work
When writing a proof, you should state your claim in a full sentence. Your proof should consist of well-organized full sentences, with references to the definitions and theorems you're using. Calculations should be clear and in the context of a sentence. For example, you could write, "We can see that 1+1=2, so by Cecily's Theorem, 1+1 is even." At the end of your proof, you should state your conclusion.
For problems that don't need a proof, you should still organize your work clearly, and justify why you can take certain steps if they're not 100% obvious. It never hurts to write full sentences in with your work.
