the value of tan 2 sec 12 cot 2 cosec 13 is 940023048

The value of $${\tan ^2}\left( {{{\sec }^{ - 1}}2} \right) + {\cot ^2}\left( {{\text{cose}}{{\text{c}}^{ - 1}}3} \right)$$ is

A. 13

B. 15

C. 11

D. None of these

Answer : 11

Solution :
Value $$ = {\sec ^2}\left( {\sec {\,^{ - 1}}2} \right) - 1 + {\text{cose}}{{\text{c}}^2}\left( {{\text{cosec}}{\,^{ - 1}}3} \right) - 1 = {2^2} - 1 + {3^2} - 1 = 11.$$
