If `(sin^(-1) x)^2 + (cos^(-1)x)^2 =(5pi^2)/8`then one of the values of x is

If (sin^(-1)x)^(2)+(cos^(-1)x)^(2)=(5pi^(2))/(8) then x =

If (sin^(-1)x)^(2)+(cos^(-1)x)^(2)=(5pi^(2))/(8) then x =

If minimum value of (sin^(-1)x)^(2)+(cos^(-1)x)^(2) is (pi^(2))/(k), then value of k is

If sin^(-1)(x^(2)-4x+5)+cos^(-1)(y^(2)-2y+2)=(pi)/(2) then find the value of x and y.

If sin^(-1) x + sin^(-1) y=pi/2 , then the value of cos^(-1) x +cos^(-1) y is :

If sin^-1 (1/5) + cos^-1(x) = pi/2 , then value of x equals :

If sin^(-1)x+sin^(-1)y=(2 pi)/(3) ,then the value of cos^(-1)x+cos^(-1)y is (A) (2 pi)/(3) (B) (pi)/(3) (C) (pi)/(2) (D) pi

If sin^(-1)x+sin^(-1)y=(pi)/(2) and sin2x=cos2y then the value of x is and sin2x=cos2y

If sin^(-1) x + cos ^(-1) y = (2pi)/5 , then cos^(-1) x + sin ^(-1) y is
