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

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

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

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

The value of int(dx)/((e^(x)+1)(2e^(x)+3)) is equal to

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

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

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

Ecaluate the following: (i) int(sec^(2)x)/(3+tanx)dx " (ii) " int(e^(x)-e^(-x))/(e^(x)+e^(-x))dx (iii) int(1-tanx)/(1+tanx)dx " (iv) " int(1)/(1+e^(-x))dx

STATEMENT-1 : int(dx)/(e^(x)+e^(-x)+2)=-(1)/(e^(x)+1)+c and STATEMENT-2 : int(d(f(x)))/((f(x))^(2))=-(1)/(f(x))+c

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