When graphing points in polar coordinates, our online polar point grapher, enables you to input angular coordinates in various units, including radians, degrees, and grades.ĭid you know you can use our powerful free online Graphing Calculator to do more and graph functions, equations, and parametric curves, in addition to graphing points? You can even use numeric expressions, such as 2/3 + sin(pi/3), for the components of a point. For example, to plot points (1, 2) and (3, 4)Įnter 1,2 3,4 (note that parentheses are excluded). To use our point grapher, simply enter the coordinates of each point, separated by a comma, and separate the points by semicolons. Our online coordinates grapher is the only coordinates plotter that allows you to rotate axes, graph points, and create line graphs in oblique coordinate systems, where the axes can be rotated to any angle and have any orientation. Our online point grapher is a powerful coordinates plotter that lets you easily plot points and create a point graph or line graph in Cartesian and polar coordinate systems. The coordinates or components of the points can be Cartesian coordinates or polar coordinates. I wanted to make the wings flap, but it was going to be pretty hard in polar form, so I converted to parametric where I could single out the x-coordinates to make the wings beat.A points grapher, also known as coordinates grapher, is a grapher that plots a set of points in a coordinate system, where the coordinates of the points are given by ordered pairs (a n, b n). One other benefit of switching polar to parametric is that in parametric form, one can do certain animations that wouldn’t have been possible in polar.įor example, check out this polar butterfly, made up of two mirror-image polar curves: Here’s what Desmos will graph:īut if we convert this to parametric, we can see the entire curve! Or let’s look at this polar function with a period of 17π. Now check it out with positive andnegative values of t: Here it is for only positive values of θ, or t, after the polar-to-parametric conversion : Let’s take another look at that spiral, using parametric equations instead of polar.

This is fantastic if you want to graph something where the curve won’t be complete after 12π radians. Notice that it allows you to specify a domain. In Desmos, parametric equations are written as an ordered pair, kind of like a point: However, if you put them into Desmos like this, you won’t get the graph you expected at all. In order to define x and y independently of each other, we will use the polar-to-rectangular conversion as follows:ĭesmos requires parametric equations to be written in terms of the parameter t and not θ, like you see below. The idea is just that you have separate equations to define what x is doing and what y is doing. These little guys are the bread and butter of so much of the amazing stuff that can be graphed on Desmos. If you’re unfamiliar with parametric equations, this is truly your lucky day.

Never fear! You CAN view a polar graph for any values of θ that you want, you just have to convert it to parametric first.įor my example of how to convert polar to parametric, I’ll use this pretty little curve. For example, what happens when θ is negative? What about for larger values of θ?

This suffices for many basic graphs, but even in the case of this spiral, it means that we aren’t seeing the whole picture. As far as I can tell, it will only draw polar graphs for values of θ from 0 to 12π radians: But as of right now, you cannot specify the domain of a polar function on Desmos. And when you graph them on Desmos, they’re simply stunning. The curves polar functions generate are fun and unexpected. This post may help to explain one of the reasons behind my change of heart. What’s your favorite type of equation? I have always loved polar equations, but in the last year or so, parametric equations have taken polar’s place as #1. (hint: it involves a quick switch to parametric equations.) In today’s post: a work-around for specifying the domain of a polar functions.
