dy/dx for parametric curves
This interactive figure allows you to explore the geometric interpretation of the derivative (slope of tangent line) for a curve defined by parametric equations.
Input parametric equations. Then, input any t-value between tmin and tmax to yield a point . This figure will then display the derivative, dy/dx, at the indicated point on the curve defined by these parametric equations. (You can also use the blue slider to change the values of t).
