Graphing Calculator

Desmos - https://www.desmos.com/ - is a good platform for maths educators and learners. 

Desmos is a graphing calculator that allows users to...

• easily plot functions,
• create tables,
• add sliders,
• animate graphs 

...and many more. 

Some of the features Desmos provides to users include...

1. Graphing: Plot polar, cartesian, or parametric graphs. There’s no limit to how many expressions users can graph at one time
2. Sliders: Adjust values interactively to build intuition, or animate any parameter to visualize its effect on the graph
3. Tables: Input and plot data, or create an input-output table for any function
4. Statistics: Find best-fit lines, parabolas, and more.
5. Zooming: Scale the axes independently or at the same time with the pinch of two fingers, or edit the window size manually to get the perfect window.
6. Points of Interest: Touch a curve to show maximums, minimums, and points of intersection. Tap the gray points of interest to see their coordinates. Hold and drag along a curve to see the coordinates change under your finger.
7. Scientific Calculator: Just type in any equation you want to solve and Desmos will show you the answer. Desmos can handle square roots, logs, absolute value, and more.
8. Inequalities: Plot cartesian and polar inequalities"
