Equations of Circles (Standard Form) & Graphing Circles

Hello there! Today's video is about circles. Remember in a previous video how I derived the distance formula from the pythagorean theorem? If you didn't watch the video, here it is: https://rumble.com/vugjvs-deriving-and-using-the-distance-formula.html

For the first portion of this video, I walk you through how the circle formula is related to the distance formula. It's always helpful to understand where the formula is from so we can remember it accurately. In the remainder of the video, I go over different types of practice problems that help you understand circles better. It's nice to know "Completing the Square" by the way so brush up on your skills wit this video: https://rumble.com/vqd122-completing-the-square-vertex-form.html
