Intro to Plane Curves & Parametric Equations Examples | Calculus 2 - JK Math

Example Problems For How to Sketch Plane Curves & Eliminate the Parameter (Calculus 2)

In this video we look at practice problems of sketching plane curves with parametric equations. We use the method of eliminating the parameter to find the corresponding rectangular equation to aid in sketching the curve, and find the initial point and terminal point of the curve when applicable to complete the sketch with a direction. We also look at examples of finding sets of parametric equations for a given rectangular equation or for a set of specific requirements/characteristics of a plane curve.

This video series is designed to help students understand the concepts of Calculus 2 at a grounded level. No long, boring, and unnecessary explanations, just what you need to know at a reasonable and digestible pace, with the goal of each video being shorter than the average school lecture!

Calculus 2 requires a solid understanding of calculus 1, precalculus, and algebra concepts and techniques. This includes limits, differentiation, basic integration, factoring, equation manipulation, trigonometric functions, logarithms, graphing, and much more. If you are not familiar with these prerequisite topics, be sure to learn them first!
