What is int (e^(x) (1 + x))/(cos^(2) (xe^(x))) dx equal to ? where c is a constant of integration

int((x+1)e^(x))/(cos^(2)(xe^(x)))dx=?

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

int(e^(x)-sin x)/(cos x+e^(x))dx

int (e^(x)+e^(-x))^(2)*(e^(x)-e^(-x))dx is equal to

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