i dont know how im supposed to get a number answer out of it

You get the McLaurin series up to the term in then you can differentiate term by term ten times (which is easy as the terms with exponent of less than will be eliminated by the time you have taken the 10-th derivative) and then set to evaluate (the terms with powers greater than when is set to zero will be zero so there was no need to look at them).

Im not sure how to do the Maclaurin series

how do i get a number if i plug in x^2/4

so i differntiated x^2/4- x^6/12 + x^10/20 ten times and all i got is 181440 which is not right

The 10th derivatives of the first two terms are zero for any value of x, and the 10th derivative of every term beyond evaluates to zero at x=0.

so

which of course at is
