These online calculators find the equation of a line from 2 points. Whether you’re interested in form, function, or both, you’ll love how Desmos handles parametric equations. It's a powerful feature that allows plotting complex graphs with 3 simple equations. Simply enter coordinates of first and second points, and the calculator shows both parametric and symmetric line equations. Parametric Equations and Polar Coordinates. In this section we will discuss how to find the area between a parametric curve and the x-axis using only the parametric equations (rather than eliminating the parameter and using standard Calculus I techniques on the resulting algebraic equation). So in general we can say that a circle centered at the origin, with radius r, is the locus of all points that satisfy the equations With Graphing Calculator 3D you can plot parametric surface or line in 3D and set the desired range for u and v parameters. Sketch the curves described by the following parametric equations : Graph of the plane curve described by the parametric equations in part a. Slope Intercept Form. Log InorSign Up. Parametric equations are used in Pre-calculus and Physics classes as a convenient way to define x and y in terms of a third variable, T. If you are familiar with the graphing function on your TI-84 calculator, then parametric equations shouldn’t be too much of a challenge for you. When we parameterize a curve, we are translating a single equation in two variables, such as [latex]x[/latex] and [latex]y [/latex], into an equivalent pair of equations in three variables, [latex]x,y[/latex], and [latex]t[/latex].
