1. The problem statement, all variables and given/known data I want to deal with this int((5+10y^4)dy/(y+2y^5)) 2. Relevant equations integration, substitution, partial fractions? 3. The attempt at a solution I tried a bunch of random things. I think it hs to do with substitution because if I make u=y+2y^5, du/dy=1+10y^4 which is strikingly similar to the numerator, so there must be a cancellation. this integral is part of a dif equation, but i cant see to go past this! i know for sure this is the correct set up because i used my calculator to integrate and it solved the differential equation.
