Houghton Mifflin: Math Graphs: Parametric Equations 1 [Pdf]

Students explore the concept of linear equations.  In this linear equations worksheet, students graph linear equations using tables of values.  Students graph 16 linear equations.

Students explore the graph of a line given by a parametric equation. Topics explored are the orientation and coordinates of the equation. The exercise consists of an enlarged printable version of a graph available in PDF format.

This detailed presentation starts with a review of using key components to graph a line. It then quickly moves into new territory of taking these important parts and teasing them out of a word problem. Special care is...

As an introduction to parametric equations, Sal solves the problem of finding the path of a car that drives off a 50-meter-high cliff while traveling five meters per second. He uses a pair of equations: x(t) = 10 + 5t and y(t) = 50 Ð...

Viewers will learn how to graph lines, such as y=2x+1. The instructor emphasizes the relationship between the x and y variables, creates an x/y table, and finally graphs the equation. A total of three examples are given in this video.

Following his intuitive manner, Sal considers another set of parametric equations. This time, he looks at two equations using trigonometric functions and, using one of the basic trigonometric identities, removes the parameter from the...

In a follow-up to the problem presented in the last video, Sal considers whether other parametric equations move along the same path as the last equations. He shows that taking a multiple of time changes the speed of the position along...

In this well-presented video, Sal continues with the example of the car driving off the cliff and discusses how the time (t) should be bound based on the context of the problem. He then shows how to rewrite the set of parametric...

Trigonometry, art, and Valentine's Day come together in a creative activity about parametric equations. Learners calculate several equations before graphing them either by hand, on a graphic calculator, or Excel spreadsheet to curve...

So, exactly, what does it look like? The easily usable graphing calculator allows pupils to visualize the graph of equations and inequalities. The interactive supports any algebraic graph needed for high school mathematics and then some.
