pleas sir i want exactly ∫(dy/(y^3 −c^3 ))=−x   in this solution ?
$${pleas}\:{sir}\:{i}\:{want}\:{exactly}\:\int\frac{{dy}}{{y}^{\mathrm{3}} −{c}^{\mathrm{3}} }=−{x}\: \\ $$$${in}\:{this}\:{solution}\:? \\ $$

(1/(y^3 −c^3 ))=(A/(y−c))+((By+C)/(y^2 +cy+c^2 ))  then you can apply known formulae.
$$\frac{\mathrm{1}}{{y}^{\mathrm{3}} −{c}^{\mathrm{3}} }=\frac{{A}}{{y}−{c}}+\frac{{By}+{C}}{{y}^{\mathrm{2}} +{cy}+{c}^{\mathrm{2}} } \\ $$$${then}\:{you}\:{can}\:{apply}\:{known}\:{formulae}. \\ $$
