This video explains how to graph exponential functions by modeling cutting a string. It demonstrates the concept of exponential decay and shows how the length of the string decreases exponentially with each cut. The video also explains...

In this video, the teacher explains how to identify line symmetry in irregular polygons. They discuss the three options for line symmetry - horizontal, vertical, and diagonal - and emphasize the importance of having matching parts when...

A derivation of the distance formula.

This video explains how to find the distance between two points on a plane without using a measuring tool. It introduces the Pythagorean theorem and demonstrates how to create a right triangle using the given points. By applying the...

In this lesson, students will learn how to accurately describe the location of places in a city using a coordinate plane. By moving on the X and Y axes, students can plot points that represent the distance and direction of various...
