Si(x)=integral(sint/tdt) from 0 to x
integrand is 1 at t=0
express the solution y(x) of the initial value problem x^3y'+2x^2y=10sinx, y(0)=0 in terms of Si(x).
What I have done:
multiply by x^2
Now I get stuck because I feel like this can't be integrated and I don't think i can just insert Si(x) because I need to account for 10x^-2.
