Homework Help: Convertong polar equations to rectangular eq.

  1. Apr 13, 2007 #1
    1. The problem statement, all variables and given/known data
    (theta)= 45Degrees

    2. Relevant equations
    (theta)= Arctan(y/x) (x>0)
    (theta)= Arctan(y/x) (x<0)

    3. The attempt at a solution

    1 = y/x
    Does that mean Y = X?

    Yes, it does! If you are not convinced, draw an xy- coordinate system, mark the line at 45 degrees to the positive x-axis and draw the line y= x!
