Get started with the video on the right, then dive deeper with the resources below. Starting off with a recent creation in Desmos, Here is an array of 200 exponential functions bounded by a circle, and a straight line through the middle.If you haven't worked with Desmos yet and you're interested in geometric and mathematical designs, it's a powerful and easy to use online graphing calculator with many useful bells and whistles. Jul 28, 2013 · When using a graphing calculator like a TI-83 or TI-84, students would also need to know how to re-write their circle equations for y in terms of x so they can actually enter them. (This would be one advantage of using Desmos over a graphing calculator; such a conversion isn't necessary. Mar 21, 2018 · In this lesson I will show you how to draw a semi-circle in DESMOS. In this lesson I will show you how to draw a semi-circle in DESMOS ... Equations of Semi-Circles - Duration: 2:01. Eddie Woo ... The equation of a circle appears as This is called the center-radius form (or standard form) because it gives you both pieces of information at the same time. The h and v represent the center of the circle at point (h, v), and r names the radius.
