16. `int(x)/(e^(x))dx`

int(x)/(e^(x^(2)))dx

Evaluate: int(e^x)/(1+e^(2x))dx

Evaluate: int(e^x)/(1+e^(2x))dx

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

int x^(2)e^(x)dx

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

Evaluate: inte^(2x)/(1+e^(4x))dx

If int(x)/(x+1+e^(x))dx=px+qln|x+1+e^(x)|+c , where c is the constant of integration, then p+q is equal to

int(e^x+1/(e^x))^2\ dx

int x^(2)e^(-x)dx
