How do I convert the polar equation r  3cos(theta) = 5sin to cartesian equation form?

Reiny,
For your equation
r  3cosØ = 5sinØ
√(x^2 + y^2)  3x/r = 5y/r
√(x^2 + y^2) = 5y/r + 3x/r
√(x^2 + y^2) = (5y + 3x)/r
√(x^2 + y^2) = (5y + 3x)/√(x^2 + y^2)
cross multiply
x^2 + y^2 = 5y + 3x
which looks like the equation of a circle to me
