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!
Or if you know how to express sinh(x) in terms of exponentials, and you know the Taylor series for exp(x).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.
