Taylor Polynomials

2. We have to take the first 3 derivatives of the tangent function:


Then we plug in tex2html_wrap_inline333


to obtain the desired approximation:


Have you noticed? An odd function has Taylor polynomials with only odd powers. Guess what happens when a function is even! Maybe you can use that in the next problem.
