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

Choose the correct answer of the given question int (e^x+1)/(e^x-1) dx = ___ +c

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

Column I, a) int(e^(2x)-1)/(e^(2x)+1)dx is equal to b) int1/((e^x+e^(-x))^2)dx is equal to c) int(e^(-x))/(1+e^x)dx is equal to d) int1/(sqrt(1-e^(2x)))dx is equal to COLUMN II p) x-log[1+sqrt(1-e^(2x)]+c q) log(e^x+1)-x-e^(-x)+c r) log(e^(2x)+1)-x+c s) -1/(2(e^(2x)+1))+c

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

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

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

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

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

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

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