`int(2x^2+x-2)/(x^2+1)dx`

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

Evaluate: int(2x^2+7x-3)/(x^2(2x+1))\ dx

Evaluate: int(2x^2+7x-3)/(x^2(2x+1))\ dx

int(x)/(2x^4-2x^2-1)dx=

int((x^2+2))/((x^2+1)(x^2+4))dx (for 0 < x < 1)=

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

Evaluate: int(x^2+2)/((x^2+1)(x^2+4))dx

If int(2x^2+3)/((x^2-1)(x^2+4))dx=alog((x-1)/(x+1))+btan^(- 1) (x/2)+C then the values of a and b are respectively (A) 1/2,1/2 (B) 1,1 (C) 1/2,1 (D) None
