int(e^((1)/(x)))/(x^(3))dx

int(e^(3x))/(e^(x)+3)dx

int(3e^(x))/(1-e^(x))dx

int(3e^(x)-4)/(e^(x)+1)dx=

Evaluate: int(e^(3x))/(e^(3x)+1)dx

Evaluate: int(e^(3x))/(e^(3x)+1)dx

Evaluate (i) int(xe^(x))/((x+1)^(2))dx (ii) int x^3e^(-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))/((1+x)^(3))dx-int(e^(x))/(2(1+x)^(2))dx=

int (e^(3x)+1)^2 e^(3x)dx
