Polar equation of a simple parametric

  1. Sep 8, 2010 #1
    1. The problem statement, all variables and given/known data
    Write the polar equation for the graph y = x.

    2. Relevant equations
    [tex]x = r cos \theta [/tex]
    [tex]y = r sin \theta [/tex]

    3. The attempt at a solution

    I came up with [tex]\theta = \pi/4[/tex] because at [tex]\pi/4[/tex], the x and y coordinates match each other. I'm not sure this is correct, though.

    Yes, that should be correct.
