The number of solution(s) of the equation, sin − 1 x + cos − 1 (1 − x) = sin − 1 ( − x), is
Text Solution
Verified by ExpertsThe correct answer is:
1
(1)
Sol. sin − 1 x + cos − 1 (1 − x) = sin − 1 ( − x)
2sin − 1 x + cos − 1 (1 − x) = 0 here 
for 
, 2sin − 1 
and cos –1 (1– x) 
There sum is equal to zero when both terms equal to zero it gives x = 0 is only solution.
