replace x by -x in given eq.
asin-1(-x) -bcos-1(-x) =c
-asin-1(x)-bcos-1(x)=c
asin-1(x)+bcos-1(x)= -c
Thanks & Regards

but options are
  1. 0
  2. [(pi)ab+c(b-a)]/(a+b)
  3. pi/2
  4. [(pi)ab+c(a-b)]/(a+b)

asin^-1 x - bcos^-1 x = c 
We have  
bsin^-1 x + bcos^-1 x = b(pi)/2
(a+b)sin^-1 x 
  = b(pi)/2 + c
sin^-1 x =( b(pi)/2 + c)/a+ b
cos^-1 x= [(pi)ab + c(a-b)]/a+b
