Homework Help: Simple vector function problem, find slope of tangent?

  1. Jun 8, 2012 #1
    1. The problem statement, all variables and given/known data

    Show that the curve r = (t2,t3-t) Intersects itself at (1,0), and find the slopes of the tangents at this point.

    2. Relevant equations

    3. The attempt at a solution

    Okay I can show it intersects itself there, but what I am having trouble with is when they say slopes of the tangents at this point .What do they mean? The wording sort of confused me.

    Hi rounded 2∏,
    How did you show they intersect ?
    I don't see anything wrong in the wording, so I just want to make sure you got it right from the beginning.
    If you did, well, the slope is dy/dx which you should be able to evaluate simply at those two "events".
