Review session (December 6)
Here is the highly non-organized review session HANDOUT. There are 52 problems and, coincidentally, my birthday is May 2! Here is the ANSWER KEY. All possible mistakes are on me. Please email me if you find something wrong.

Some Graphs about Taylor Series, Fourier Series, Fourier Sine Series, and Fourier Cosine Series:

Taylor series for exponential function (Classical but most important)
Taylor series for sine function and cosine function (Also classical)

For Fourier series, the interval matters a lot! Try to figure out what L is, sometimes it is 1 or 1/2 or pi or 2pi.
Fourier series for y=x (Simplest among Fourier)
Fourier series for a step function (Second simplest among Fourier)
Fourier series for a laptop-side-view function (First example of non-symmetric) and here is the same thing but up to N=40. It also looks like a very thin sofa or an extremely inclined chair(?).
Comparison of three types of Fourier series for y=-x^9+x+1 (It's just a randomly picked function)
Comparison of three types of Fourier series for y=x^2-x+1 (Also a randomly picked function)

Here is the pdf file.
