If x in[0,6 pi],y in[0,6 pi] then the number of ordered pair (x,y) which satisfy the equation sin^(-1)sin x+cos^(-1)cos y=(3 pi)/(2) are

The value of cos y cos ((pi)/(2) - x) - cos ((pi)/(2) - y) cos x + sin y cos ((pi)/(2) - x) + cos x sin ((pi)/(2) - y) is zero if

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

Solve : sin^-1 x+sin^-1 y=(2pi)/3 cos^-1 x-cos^-1 y=pi/3

Given 2sin x+3cos y=3,3sin y+2cos x=4;(x,y in(0,(pi)/(2))) then

What is the value of {sin(90 -x)cos [pi - (x -y)]} + {cos (90- x) sin [pi- (y- x)]} ? {sin(90 -x)cos [pi - (x -y)]} + {cos (90- x) sin [pi- (y- x)]} का मान क्या है?

If ( sin x) (cos y) = 1//2, then d^(2)y//dx^(2) at (pi//4, pi//4) is
