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

Draw the graph of y = sin^(-1)2x" and "y=sin^(-1)(x//2)" and compare with " y = sin^(-1)x .

Draw the graph of y = sin^(-1)2x" and "y=sin^(-1)(x//2)" and compare with " y = sin^(-1)x .

If "cos"^(-1)x+"cos"^(-1)y=(2pi)/(7) , then the value of "sin"^(-1)x+"sin"^(-1)y is

If "cosec"^(-1)x=sec^(-1)y , then the value of ("sin"^(-1)(1)/(x)+"sin"^(-1)(1)/(y)) is -

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

If sin^(-1) x + sin^(-1) y = pi/2 , prove that x sqrt(1-y^2) + y sqrt(1-x^2) =1 .

If sin^(-1) x + sin^(-1) y = pi/2 , prove that x sqrt(1-x^2) + y sqrt(1-y^2) =1 .

(sin ^ (- 1) x) ^ (2) + (sin ^ (- 1) y) ^ (2) +2 (sin ^ (- 1) x) (sin ^ (- 1) y) = pi ^ (2), then x ^ (2) + y ^ (2) is equal to
