Pre-Algebra - The Coordinate Plane

| No Comments | No TrackBacks

Are you ready for the weekend? How about a little math first?

In today's free Pre-Algebra video Professor Burger discusses The Coordinate Plane. The coordinate plane is a plane containing a horizontal number line, the x-axis, and a vertical number line, the y-axis. This particular plane is called The Cartesian Plane, due to the use of Cartesian coordinates. The name Cartesian comes from its inventor, the French mathematician and philosopher René Descartes. Interestingly enough, many people speculate that Descartes was inspired by Renaissance painters who used a grid, in the form of a wire mesh, as a tool for breaking up the component parts of their subjects they painted. We may never know the truth, but we do know that the Cartesian coordinate system aided in the development of calculus by Isaac Newton and Gottfried Wilhelm Leibniz.

Learning about the coordinate plane is the first step in graphing numbers and equations, and is used extensively throughout math and math related subjects. You will use graphs for many future math subjects as graphs can tell you much about a series of numbers.

Today's video has a total of 3 lectures covering everything from the quadrants of the coordinate plane to how to plot points on the coordinate plane given the coordinates. Don't forget to click the forward button directly to the left of the time stamp to move to the next lecture.
