Homework Help: Rectangle to Polar Form

  1. Nov 14, 2004 #1
    How would I change: 2x+3y=4
    into polar form? I understand how to solve for polar form but the 4 without a variable is confusing me.

    [tex]2 r cos \theta + 3 r sin \theta = 4[/tex]
    [tex]r(2 cos \theta + 3 sin \theta) = 4[/tex]
    [tex]2 cos \theta + 3 sin \theta = 4/r[/tex]
    [tex]\frac{4}{2 cos \theta + 3 sin \theta} = r[/tex]

    whats wrong with that?
