Homework Help: DiffEq question

  1. Nov 9, 2008 #1
    How do you multiply McLaurin functions by "regular" power series?
    For example:

    If y' = sum (1, inf.) n*a_n x^n-1 and cos(x) = sum(0, inf.) (-1^n x^2n) / (2n)!, how do you find the product?

    If y = sum(0, inf.) a_n x^n and sin(x) = sum(0, inf.) (-1^n x^(2n+1)) / (2n+1)!, how do you find the product of sin(x), y, and x?
