Help algebra.com: Rectangular Coordinates

Sal illustrates more involved equations in this last video in a series. It follows "Simple Equations" and "Equations 2". He continues using color-coded markings to help increase students' understanding of a more complicated equation:...

Learners explore the Pre-Calculus topic of polar and rectangular coordinates. The activity has several examples with detailed solutions.

The sequel to Polar Coordinates 1 from the Khan Academy, this segment goes through some examples on converting polar coordinates to rectangular coordinates and converting a Cartesian equation to a polar equation. Graphing is also used to...

Find step-by-step examples to help learn four objectives based on ordered pairs in a Cartesian coordinate system.

Do you know the formula needed to determine the area of a rectangular prism? If you don't it's ok, because this video will refresh your memory, then help you use the formula to find the volume of a rectangular prism. Algebra is used to...

Students learn about the rectangular coordinate system and graphing. The learning resource consists of a video tutorial and a worksheet with practice problems. In the left hand menu, click Trigonometry, Trigonometric Functions.

Here is a site that clearly and thoroughly explains the Cartesian coordinate system. There are example problems solved, problems for the student to attempt, and answers to the student problems. Point this site out to students who have...

Investigate vectors in standard positions and use the CellSheet application on the TI calculator to find the sum of two vectors. Convert from polar to rectangular coordinates and vice versa, and show graphs of the vectors.

Examples and a video tutorial teach how to draw ordered pairs in the coordinate plane. [1:30]

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...
