2cos^(-1)x=cos^(-1)(2x^(2)-1)

f(x)=sin^(-1)[x^(2)+(1)/(2)]+cos^(-1)[x^(2)-(1)/(2)] where [.1 denotes the greatest integer function.

If [.] denotes the greatest integer function, then find the value of [sin^(-1)[x^(2)+1/2]+cos^(-1)[x^(2)-1/2]]

The range of sin^(-1)[x^(2)+1/2] + cos^(-1)[x^(2)- 1/2] , where [.] denotes the greatest integer function, is

The value of a for which ax^(2)+sin^(-1)(x^(2)-2x+2)+cos^(-1)(x^(2)-2x+2)=0 has a real solution is
