c o s [ c o s − 1 ( − 1 7 ) + s i n − 1 ( − 1 7 ) ] = Options: A . &nbsp−13 B . &nbsp0 C . &nbsp13 D . &nbsp49

Answer: Option B : B c o s { c o s − 1 ( − 1 7 ) + s i n − 1 ( − 1 7 ) } = c o s π 2 = 0

cos[cos−1(−17)+sin−1(−17)]=

Question

c o s [c o s^{- 1} (\frac{- 1}{7}) + s i n^{- 1} (\frac{- 1}{7})] =

Options:

A . −13

B . 0

C . 13

D . 49

Answer: Option B
:
B

c o s {c o s^{- 1} (\frac{- 1}{7}) + s i n^{- 1} (\frac{- 1}{7})} = c o s \frac{π}{2} = 0
