If your device is not in landscape mode many of the equations will run off the side of your device (should be able to scroll to see them) and some of the menu items will be cut off due to the narrow screen width.
Assignment Problems Notice
Please do not email me to get solutions and/or answers to these problems. I will not give them out under any circumstances nor will I respond to any requests to do so. The intent of these problems is for instructors to use them for assignments and having solutions/answers easily available defeats that purpose.

If you are looking for some problems with solutions you can find some by clicking on the "Practice Problems" link above.

### Section 10.17 : Applications of Series

1. Determine a Taylor Series about $$x = 0$$ for the following integral. $\int{{\frac{{\cos \left( x \right) - 1}}{x}\,dx}}$
2. Write down $${T_2}\left( x \right)$$, $${T_4}\left( x \right)$$ and $${T_6}\left( x \right)$$ for the Taylor Series of $$f\left( x \right) = \sin \left( x \right)$$ about $$\displaystyle x = \frac{{3\pi }}{2}$$. Graph all three of the Taylor polynomials and $$f\left( x \right)$$ on the same graph for the interval $$\left[ { - \pi ,2\pi } \right]$$.
3. Write down $${T_2}\left( x \right)$$, $${T_3}\left( x \right)$$ and $${T_4}\left( x \right)$$ for the Taylor Series of $$f\left( x \right) = \ln \left( {1 - x} \right)$$ about $$x = - 2$$. Graph all three of the Taylor polynomials and $$f\left( x \right)$$ on the same graph for the interval $$\left[ { - 4,0} \right]$$.
4. Write down $${T_1}\left( x \right)$$, $${T_3}\left( x \right)$$ and $${T_5}\left( x \right)$$ for the Taylor Series of $$f\left( x \right) = \frac{1}{{{{\left( {6 - x} \right)}^7}}}$$ about $$x = 4$$. Graph all three of the Taylor polynomials and $$f\left( x \right)$$ on the same graph for the interval $$\left[ {1,5} \right]$$.
5. Write down $${T_2}\left( x \right)$$, $${T_4}\left( x \right)$$ and $${T_6}\left( x \right)$$ for the Taylor Series of $$f\left( x \right) = \sqrt {2 + x}$$ about $$x = 1$$. Graph all three of the Taylor polynomials and $$f\left( x \right)$$ on the same graph for the interval $$\left[ { - 2,4} \right]$$.
