If `(2x+1)/((x+1)(x+2))`=`A/(x+1)`+`B/(x+2)`then (A,B) is equal to

If (2x+5)/((x-1)(x-2))=(A)/((x-1))+(B)/((x-2)) then (A,B) is

If A = (2x + 1)/(2x - 1) and B = (2x - 1)/(2x + 1) then A - B is equal to:

Let sin^(-1)((2{x})/(1+{x}^(2)))=A+B tan^(-1)({x}) then A-B is equal to

If (3)/((x+2)(2x+1))=(a)/(2x+1)+(b)/(x+2) then b= ?

If f(x)=|\(1,x,x+1),(2x,x(x-1),(x+1)x,3x(x-1),x(x-1)(x-2),(x+1)x(x-1))| then f(100) is equal to (A) 0 (B) 1 (C) 100 (D) -100

If int (x^4 + 1)/(x(x^2+1)^2)\ dx = A ln |x| +B/(1+x^2)+C, then A+B equals to :
