Need help to finish my homework

  1. May 3, 2008 #1
    Need answers for 2 questions please:

    1.) Find the equation of the line tangent to the curve at the point.

    xy + y = 2 ; (1,1)

    2.) Evaluate dy/dt for the function at the point

    xy^2 = 4 dx/dt = -5 x = 4, y = 1

    Thank You

    You need to show us an attempt at a solution before we can help you. But I'll tell you that you need implicit differentiation for this.
