Question

tan A=1|2 and tan B =1|3 then the value of A+B is

Answer 1

Use tan sum formula to express tan(A+B) in terms of Tan A and Tan B and then A+B is arctan that.

Answer 2

\[A+B=\tan^{-1}((\tan A+\tan B )/(1-\tan A*\tan B))\]
tanA=1/2,tanB=1/3
\[A+B=\tan^{-1} (5/6*6/5)\]
\[A+B=\Pi/4\]
i hope u unterstood
