`int (2x+3)/((x+2)(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

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

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

int (dx)/((x+1)(2x+1)) (ii) int (x-1)/((x-2)(x-3)) dx .

int(2x+3)/(3x+4)dx

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

Evaluate: int(x^3-3x)/(x^4+2x^2-4)\ dx

Evaluate: (i) int(x^(2)+x+5)/(3x+2)dx (ii) int(2x+3)/((x-1)^(2))dx

If : int(2x^(2)+3)/((x^(2)-1)(x^(2)-4))dx=log[((x-2)/(x+2))^(a).((x+1)/(x-1))^(b)]+c then : (a, b)-=

int(2x^(2)+3)/((x^(2)-1)(x^(2)+4))dx=alog((x+1)/(x-1))+b"tan"^(-1)(x)/(2) , then (a,b) is
