Quick power series question

Hi I was wondering if anyone could guide me through this question:

Find a power series representation of the function of using termwise integration of the Maclaurin series for sin x. For which xER is this representation valid.

Thank you in advance :)

Don't you know the MacLaurin series for sin(t)? Just divide every term by t, then integrate...
