Homework Help: Taylor series problem (non-direct differentiation?)

  1. Feb 18, 2014 #1
    I attached a picture of the problem from my online HW. I know how to solve the problem through direct differentiation, but that would too long to find the derivatives for this problem, and the problem actually suggests that I find another way. So my question is, what's the best way to solve this?

    Multiply the Taylor series of [itex]\sin(7x)[/itex] by [itex]x^3[/itex].
