If `xy != 0` and `sqrt((xy)/(3)) = x`, what is y?
(1) `x/y = 1/3`
(2) `x = 3`

If (x + y) ^(2) = xy +1 and x ^(3) -y ^(3) = 1, what is the value of (x-y) ?

If 1//x + 1//y = 1//3 ,then (xy)/(x + y) =

If y = (sin^(-1) x)/(sqrt(1-x^2)) show that (1-x^2) y_2 - 3xy_1 - y =0

If x = 2+ sqrt3, y = 2- sqrt3 and z = 1, then what is the value of (x//yz) + (y//xz) + (z//xy) + 2[(1//x)+ (1//y) + (1//z)] ?

If x = 2 + sqrt3, y = 2 - sqrt3 , then find the simpliest value of (a) x - (1)/(x) , (b) y^(2) + (1)/(y^(2)) , (c) x^(3) - (1)/(x^(3)) , (d) xy + (1)/(xy)
