If `sin^-1 x + sin^-1 y = (2pi)/3,` then `cos^-1 x + cos^-1 y =`

If sin^-1 x+sin^-1=(2pi)/3, then cos^-1 x cos^-1 y is equal to

If sin^-1 x+sin^-1=(2pi)/3, then cos^-1 x cos^-1 y is equal to

If sin^-1 x+sin^-1=(2pi)/3, then cos^-1 x cos^-1 y is equal to

If sin^-1 x + sin^-1y = pi/2 , then value of cos^-1 x + cos^-1 y

If sin^-1x+sin^-1y=(2pi)/3 , then cos^-1x+cos^-1y =

If sin ^(-1) x + sin ^(-1) y = (pi)/(6) , then cos^(-1) x + cos ^(-1) y =?

If sin ^(-1) x + sin ^(-1) y = (pi)/(6) , then cos^(-1) x + cos ^(-1) y =?

(i) Evaluate : sec (cos^(-1).(1)/(2)) (ii) slove the equations sin^(-1) x + sin^(-1) y = (2pi)/(3) and cos^(-1) x - cos ^(-1) y = (pi)/(3)

If sin^(-1) x + sin^(-1)y = pi//2 and cos^(-1) x - cos^(-1) y = 0 , then value x and y respectively
