If `cos e c^(-1)x+cos e c^(-1)y+cos e c^(-1)z=-(3pi)/2,`find the value

1.	If `cos e c^(-1)x+cos e c^(-1)y+cos e c^(-1)z=-(3pi)/2,`find the value of `x/y+y/z+z/xdot`
Answer» `cosec^-1 x=> [ -pi/2,0) uu (0, pi/2]` `cosec^-1 x = -pi/2` `cosec^-1 y = -pi/2` `cosec^-1 z = -pi/2` `x= -1` `y= -1` `z=-1` `=> x/y + y/z + z/x` `-1/-1 + -1/-1 + -1/-1` = `1 + 1 + 1 = 3` Answer
