# Solve que 79 as fast as possible. ​Q79. If A = 2 tan–1         (A) B < A < $\frac{7\mathrm{\pi }}{12}$                    (B) $\frac{7\mathrm{\pi }}{12}$ < B < A               (C) B < $\frac{7\mathrm{\pi }}{12}$< A           (D)$\frac{7\mathrm{\pi }}{12}$< A < B

i would advice you to put the respective values of the inverse trignometric functions and then compute the ans.
sin-13/5 = 370
sin-11/3=150
tan-1(23/2-1)= 620
then option c is correct
even such kind of questions are most probably meant for the competitives only.
