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

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

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

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

If tan A = frac{1}{sqrt (x(x^2 x 1)} , tan B = frac{sqrt x}{sqrt (x^2 x 1)} , and tan C = (x^(-3) x^(-2) x^(-1))^(1/2) , 0 < A, B, C < pi/2 , then A B is equal to :

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