Use the series expansions for $\displaystyle e^x$ and sin(x) to find a series

expansion forsin($\displaystyle e^x$)up to terms in x$\displaystyle ^3$ .

Use your series to approximate

stating the error in your approximation.

ok i have the series expansion for

how do i combine the two series to get sin(e^x).

also what does it mean by stating the error of approximation.
