    Converting Cartesian to Polar Coordinates: How Do We Get r and Theta?

    Homework Statement Write equation in polar form. y=3x+4 Homework Equations x^2 + y^2 = r^2 x = rcos(theta) y = rsin(theta) tan(theta) = y/x The Attempt at a Solution Square both sides... y^2 = 9x^2 + 24x + 16 r^2 - x^2 = 9x^2 +24x +16 r^2 = 10x^2 + 24x + 16 And...
