Tangent line to a curve

  1. Oct 16, 2007 #1
    1. The problem statement, all variables and given/known data
    Find the tangent line to the curve y^2 (y^2 - 4) = x^2 (x^2 -5) at the point (0,-2).

    2. Relevant equations

    3. The attempt at a solution
    I d/dx-ed both sides and was left with dy/dx=0
    Does that seem right?
