Parametric Equations and slope

  1. Mar 3, 2015 #1
    1. The problem statement, all variables and given/known data
    Find all the points on the following curves that have the given slope:


    2. Relevant equations

    3. The attempt at a solution
    Im not to sure what to do with this question.. I found dy/dx to be -cot(t) but im not sure if that is even needed for this problem. Any help would be greatly appreciated !

    That's a good start. Now just set -cot(t) = 1/2 and solve for t.

    BTW, your parametric equations represent one curve, not multiple curves.
