find the first three non zero terms of a power series representation of f(x)= sinh 2x
The Attempt at a Solution
seems easy enough do I just substitute 2x for x?
so sinh 2x= 2x + 8x3/3! + 32x5/5!
You didn't really need to have the formula on your cheat sheet if you know how to differentiate sinh(2x). Just use the general formula for a Taylor series.
