I shall be glad if someone will assist me in finding an answer to the problem

I = integral (2b*y^2*dy) / (a+by+cy^3)

a,b,c are constants.

partial fractions:

begin by factoring the denominator…

Maple says:

/ —– \

| \ / 2 \|

| ) |_R ln(y – _R)||

2 b | / |————–||

| —– | 2 ||

| \ b + 3 c _R /|

\_ /

where the sum is over all three zeros _R of a+b*y+c*y^3
