# Online Graphing Calculators

**Web Link: **Desmos | Graphing Calculator

**Flexibility: **This graphing calculator has the following major features:

Ability to enter multiple expressions, expressions will automatically format as they are written out.

Ability to use equality or inequality in expressions

Typing in expressions uses common keyboard shortcuts such as ^ for exponents and _ for subscripts.

Can create sliders for non-x/y variables.

All major trigonometric functions

Ability to add tables, notes, and images. These can be stored in folders to help manage multiple expressions.

Able to use statistical/probability functions such as nCr, mean, or stdevp.

Can be used to create visualizations (histogram, dot plot, et al) or visualizations (normal distribution, binomial, et al.)

The grid can be modified to be standard or unit-circle, degrees or radians.

Axis can be modified and new labels inputted.

All graphs can be saved, shared, and retrieved later by the teacher. They can also be embedded into a webpage if needed.

A projector mode makes the grid easier to see from a distance by increasing line thickness and number size.

Teachers have created classroom activities that can be done through Desmos here.

**User Interfaces: **Mouse and touchpad friendly. Touch0friendly as well. Apps exist for Android and Apple devices.

**Browsers: **Works with all major browsers.

**Web Link: **Calculator Suite - GeoGebra

**Flexibility: **This graphing calculator has the following major features:

Ability to enter multiple expressions, expressions will automatically format as they are written out.

Ability to use equality or inequality in expressions

Typing in expressions uses common keyboard shortcuts such as ^ for exponents and _ for subscripts.

Can create sliders for non-x/y variables.

All major trigonometric functions

Extra ability to add text and images to the grid.

You can create a table of values based on an existing expression, but cannot independently create one.

GeoGebra enables the creation of widgets, this means that there are a lot of options for sliders, locking lines, and scripting if-then statements.

There are functions for statistics that you can use, but require listing elements in set-notation.

Any graph can be saved, shared, and created into a widget for use on a website.

Graphs can also be downloaded as images or copied to the clipboard.

GeoGebra has a vast resource of widgets and material already created and shared by teachers. You can either search or browse by major mathematical concepts here.

GeoGebra also offers several calculators that are locked down for test-taking purposes.

Typing in expressions uses common keyboard shortcuts such as ^ for exponents and _ for subscripts.

Some trigonometric functions are missing

Graphs can be saved and used later.

Symbolab may want to be avoided for the following reasons:

The app allows students to take photos of mathematical works and solves it for them. There is a paid option to show all steps in the problem.

The overall app experience is difficult to use.
