The value of c o s − 1 ( c o s 12 ) − s i n − 1 ( s i n 14 ) is Options: A . &nbsp − 2 B . &nbsp 8 π − 26 C . &nbsp 4 π + 2 D . &nbsp None of these

Answer: Option D : D c o s − 1 ( c o s 12 ) − s i n − 1 ( s i n 14 ) ⇒ 4 π − 12 + 5 π − 14 = 9 π − 26

The value of cos−1(cos12)−sin−1(sin14) is

Question -

The value of $c o s^{- 1} (c o s 12) - s i n^{- 1} (s i n 14)$ is

Options:

A .

- 2

B .

8 π - 26

C .

4 π + 2

D . None of these

Answer: Option D
:
D

c o s^{- 1} (c o s 12) - s i n^{- 1} (s i n 14) \Rightarrow 4 π - 12 + 5 π - 14 = 9 π - 26
