Homework Help: Convert to Polar Coordinates

  1. Nov 26, 2013 #1
    1. The problem statement, all variables and given/known data

    x = eKcos(k)

    -∞ < K < ∞

    Find an equation in polar coordinates for the above curve

    3. The attempt at a solution

    I am not fully clear as to what the question is asking.

    If its asking for (r,k), where K is normally a theta value then it would be (e^k,k)

    other than that,


    r^2 = e^2k

    r = √e^2k = e^k


    Any help or suggestions would be appreciated!

    r = ek is the answer you're looking for. It's an equation in polar coordinates and spans the same curve as your original parametric equations.
