I'm trying to integtrate x^3 sin x without using integration by parts. I have set up the equation to either:
int x^3 cosx dx = (Ax^3 + Bx^2+Cx+D)cos x + K
or
int x^3 coxs dx = (Ax^3+Bx)sinx + (Cx^2+D)cosx +K
but I'm having trouble... any help would be appreciated!
int x^3 cosx dx = (Ax^3 + Bx^2+Cx+D)cos x + K
or
int x^3 coxs dx = (Ax^3+Bx)sinx + (Cx^2+D)cosx +K
but I'm having trouble... any help would be appreciated!
