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

int(e^(x))/((1+x)^(3))dx-int(e^(x))/(2(1+x)^(2))dx=

int(-e^(1/x^(3))/(x^(4)))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

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 .

Evaluate the following integrals: int e^x(1/x^2-2/x^3)dx

10.(i) int e^x (1/x^2-2/x^3)dx

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

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