Desmos Test Mode Status

Points of Interest: Touch a curve to show its maximum and minimum values, intercepts, and points of intersection with other curves.  The special “ans” key always holds the value of the previous computation (and updates automatically! ), so you never have to remember or copy a result.  Arithmetic: Beyond the four basic operations, the scientific calculator also supports exponentiation, radicals, absolute value, logarithms, rounding, and percentages.  Since all of your work is held in the expressions list, you can compute a value once and use it in many places simultaneously.  Sliders: Adjust values interactively to build intuition, or animate any parameter to visualize its effect on the graph.  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 view of your graph.  Multiple Expressions: Unlike many four-function calculators, all of your previous work remains visible on the screen.  Statistics: Compute the mean and standard deviation (sample or population) of a list of data.  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!  Statistics: Use regressions to find the lines (or other curves! ) that best fit your data.  Variables: Assign values to variables that you can use in other expressions.  Take advantage of the “ans” key, which always stores the value of the previous expression.  At Desmos, we imagine a world of universal math literacy where math is accessible and enjoyable for all students.  Trigonometry: Evaluate the fundamental trigonometric functions and their inverses using either radians or degrees for angle measure.  Tables: Input and plot data, or create an input-output table for any function.  ** These are restricted versions of the Desmos Calculators that comply with exam requirements.
