then value of the expression
sin –1 (cos(cos –1 (cosx) + sin –1 (sinx))) equals
A
B
C
0
D
None
Text Solution
Verified by ExpertsThe correct answer is:
B
cos –1 cosx = cos –1 cos(2 π − x) for x ∈ 
= 2 π − x
sin –1 sinx = x – 2 π
∴ sin –1 (cos (cos –1 (cosx) + sin –1 (sinx)))
= sin –1 (cos 0) = sin –1 (1) =
