**This is a restricted, test-safe version of the Desmos Graphing Calculator. It was designed in partnership with Eanes Independent School District to be compatible with STAAR exams and other state assessments. Find out if Desmos is on your test at www.desmos.com/testing. If you’d like to use the full Desmos Calculator, download the regular Desmos Graphing Calculator App (also free!)**
Graphing: Plot polar, cartesian, or parametric graphs. There’s no limit to how many expressions you can graph at one time - and you don’t even need to enter expressions in y= form!
Sliders: Adjust values interactively to build intuition, or animate any parameter to visualize its effect on the graph.
Tables: Input and plot data, or create an input-output table for any function.
Statistics: Find best-fit lines, parabolas, and more.
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.
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.
Scientific Calculator: Just type in any equation you want to solve and Desmos will show you the answer. It can handle square roots, logs, absolute value, and more.
Inequalities: Plot cartesian and polar inequalities.
Offline: No internet access required.

Ratings and Reviews
Desmos is the best.
So glad the Desmos team took the time to create this tool. Our students are so excited to apply there knowledge of Desmos on the STAAR test!
My students are thankful!
Students love the ease of use and versatility that the “regular” Desmos app provides, so imagine their excitement when they found out they had Desmos TEST MODE access for standardized testing! Integrating the same tool used in instruction to assess student understanding on high-stakes tests was a seamless and welcome experience. Thank you, Desmos!
