Math Is Fun: Introduction to Coordinates

In this introduction to functions video, Sal intuitively defines a function and introduces the function notion f(x). He finishes the video by looking at a simple example of evaluating g(f(x)) without getting into the complexity of...

Systematically check a solution in a system. Given a point and a system, the presenter checks to see if the point is a solution to the system. Pupils understand what it means to be a solution to a system. The video shows both...

The order in ordered pairs is an important descriptor! Young scholars learn how the order of a coordinate pair helps them find its location on a Cartesian plane. The video lesson demonstrates graphing points in each quadrant and explains...

Students are introduced to concepts taught in trigonometry. The tutorial consists of notes and examples.

A complete reference guide to coordinate geometry. It provides definitions and examples that enhance further explanation. Includes links to related topics.

Learning polar coordinates does not require visiting the North Pole, though explaining igloos is much easier using polar coordinates. The lesson begins with a video explaining how to find coordinates on a spherical plane and how to...

The students will use multiple representations of undefined terms on a coordinate plane to solve problems.

Explains, with examples, what compound interest is and how to calculate it using a formula. Also shows how to work backwards to calculate the present value of an investment, how compound interest is calculated for different compounding...

Students learn about polar and cartesian coordinates. The tutorial consists of notes and examples.

Follow steps and examples to see how easy it is to convert from one unit to another using fractions.
