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 :

If lim_(xrarr1)((asin(x-1)+bcos(x-1)+4))/(x^2-1)=2 , then (a,b) is equal to

If af(x+1)+bf((1)/(x+1))=x,x!=-1,a!=b then f(2) is equal to

If lim_(x to 1) (x^(2) - ax + b)/(x-1)=5," then " a + b is equal to
