`int (1-3x)(1+x) dx`

int(3x-1)/(x+1)dx

int(1+x^(3))/(1+x)dx is equal to:

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

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

The value of int_(0)^(1) x^(3) (1- x)^(11) dx is equal to

If I_(3,8)=int x^(3)(1+x)^(8)dx=((1+x)^n)/mf(x)+C , where f(x) is a cubic polynomial with integer coefficients, then the middle digit of m equal to

Evaluate: int(3)/((1-x)(1+x^(2)))dx
