int(1+2x)^3/x^4dx

(i) int ((1+x)^(3))/(sqrt(x))dx " "(ii) int((1+x)^(3))/(x^(4)) dx

(i) int ((1+x)^(3))/(sqrt(x))dx " "(ii) int((1+x)^(3))/(x^(4)) dx

int(2x^(3))/(x^(4)+1)dx

" (5) "int(x^3)/(1+2x^(4))dx

int(2x^(3)-1)/(x^(4)+x)dx is equal to

Evaluate int (2x^(3)-1)/(x^(4)+x)dx

Prove that, int (e^(x))/(x^(4))dx=-(e^(x))/(3)[(1)/(x^(3))+(1)/(2x^(2))+(1)/(2x)]+(1)/(6)int (e^(x))/(x)dx .

int(e^(x))/(x^(4))dx=-(e^(x))/(3)[(1)/(x^(3))+(1)/(2x^(2))+(1)/(2x)]+(1)/(6)int(e^(x))/(x)dx

I=int(2x^(3)+4x+1)/(x)dx
