## Homework Statement

y

^{3}(dy/dx) = (y

^{4}+ 1)cosx

**2. The attempt at a solution**

I solved for the homogeneous equation which is y = Ce

^{-sinx}Where C is some constant

for the particular solution I tried Asinx + Bcosx where A and B are constants but when subbing in it's gets very messy.

How should I do this?

Thank you
