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

If sin^(-1)x+sin^(-1)y=(2pi)/3 then what is 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)/(6) , then cos^(-1) x + cos ^(-1) y =?

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

What are the values of (x, y) satisfying the simultaneous equation sin^(-1)x + sin^(-1)y=(2pi)/(3)and cos^(-1)x - cos^(-1)y=(pi)/(3) ?

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

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

If sin^(-1)x +sin^(-1)y =pi then cos^(-1)x +cos^(-1)y is :

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