pi tan A=(5)/(6)quad tan B=(1)/(n)quad " find "quad A+B

If tan A=(a)/(a+1) and tan B=(1)/(2a+1) then find the value of A+B=................. A) 0 B) pi/2 C) pi/3 D) pi/4

tan A=(5)/(6) andtanB =(1)/(11), prove that A+B=(pi)/(4)

If A and B are acute angles such that tan A=(1)/(2),tan B=(1)/(3) and tan(A+B)=(tan A+tan B)/(1-tan A tan B), find A+B

If tanA=m/(m-1) and tan(B)=n , find the values of tan 2A and tan 2B .

If tanA=m/(m-1) and tan(B)=n , find the values of tan 2A and tan 2B .

If A and B are acute angles, find (A+B) given tan A = (5)/(6), tan B = (1)/(11).

Simplify tan^(-1) (tan. (5pi)/6)

If tan(A+B) = m and tan (A - B) = n , find tan 2A and tan 2B in terms of m and n (mn != 1)

Given that tan(A+B)=(tan A+tan B)/(1-tan A tan B) find the values of tan75^(@) and tan90^(@) by taking suitable values
