`int dx/(x^4-1)`=

int \ x/(x^4-1)dx

int 5/(1+x^4)dx

int (dx)/(x^(2)(x^(4)+1)^(3/4))is

Deduce the reduction formula for I_(n)=int(dx)/(1+x^(4))^(n) and Hence evaluate I_(2)=int(x)/(1+x^(4))^(2) .

Evaluate : int (x)/(1+x^(4)) "dx "

Evaluate : int (x)/(1+x^(4)) "dx "

Evaluate: int1/(x^4-1)dx

int 1/(xsqrt(x^4-1))dx

int \ (2xtan^(- 1)x^2)/(1+x^4)dx

int (1+x)^4 dx
