Tangent Line to the Parametric Curve
Description
You'll find the equation of the tangent line to a parametric equation in the same way that you found the tangent line to a regular equation. The only thing that's different is how you take the derivative of a parametric curve versus a regular curve, and that you have to plug a t-value into both x(t) and y(t) to find the coordinate point that represents the point of tangency.
