`int_0^1 e^-x/(1+e^x)dx`

Evaluate the following integral: int_0^1(e^x)/(1+e^(2x))dx

What is the value of int_0^1 (x-1) e^(-x) dx

The area bounded by y=|e^|x|-e^(-x)| , the x-axis and x=1 is (A) int_0^1 (e^x-e^(-x))dx (B) e+e^(-1)-2 (C) e+e^(-1)+2 (D) (sqrt(e)-1/sqrt(e))^2

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

int_(0)^(1)x e^(x)dx=

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

int_(0)^(1) x e^(x) dx=1

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

int_(0)^(1)(e^(x))/(1+e^(2x))dx
