How do you graph y=sec(pix/4)?

Feb 3, 2018

I use a FREE online graphing calculator at the URL: https://www.desmos.com/calculator

Explanation:

Desmos allows one to graph equations like $y = \sec \left(\pi \frac{x}{4}\right)$ by entering the equation or by entering only the right side.

Here is a graph of $y = \sec \left(\pi \frac{x}{4}\right)$, using Desmos:

Desmos has the ability to export a png file type and Socratic has the ability to import a png file type.

You can, also, you the Socratic.org graphing feature in a Socratic.org scratchpad but desmos has many more features.
