Parametric Curves: Example 6: Graphing Devices

In this video I go over another example on parametric curves as well as discussing how we can write any function as a pair of parametric equations, which we can then graph out. The example I go over is graphing the function x = y^4 -3y^2 which although can be plotted normally, I rewrite it as a pair of parametric equations by setting t = y. Thus the equations become x = t^4 - 3t^2 and y = t. This makes it possible to track a particle as it follows the path of the curve.

In general any function can be written as a pair of differential equations by first setting a parameter t to equal either x or y. Parametric equations makes it possible to graph very complicated, and near impossible to manually sketch, curves. I go over a few of them and show just how amazing some of the curves that can generated. I also use the Desmos online graphing calculator to illustrate how to graph parametric curves and to trace how the particle moves across them.

This is an incredibly cool video on parametric videos, and the amazing graphs that can be produced has been the driving force for me to pursue deeper into mathematics. This is one of my favorite topics, so make sure to watch this video!
