Homework Statement
y3(dy/dx) = (y4 + 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
