Math Tools Activities
November 2021
  • Polygons can now be assigned to variables, used as part of function definitions, and stored in lists.
October 2021
  • Added list comprehensions to the graphing calculator. You can now create new lists based on existing lists using a variety of operations. Learn more.
August 2021
  • Added Actions to the graphing calculator. Actions provide a way to react to events in the calculator, like clicks or clock ticks, by updating variables in the expression list. Learn more.
July 2021
  • The way that math is read when using a screen reader has been updated to speak shorter forms of common numeric fractions and exponents.
  • Improved the keyboard accessibility of static labels in the graphing calculator.
  • Removed the panning effect for audio trace of graphs in the form \(x=f\left(y\right)\).
  • Fixed bugs in the graphing calculator related to the stacking order for moveable points, expressions nested too deeply, opacity of labels, and the round( ) function.
June 2021
  • Fixed bugs in the graphing calculator related to opacity of labels on lists of points, voice over accessibility for regressions, and pasting data into tables.
May 2021
  • Added a unique( ) function to the graphing calculator that takes a list and returns a new list without duplicates.
  • Updated the undo/redo stack size in the graphing calculator from 20 to 100.
  • Fixed bugs in the graphing calculator related to the redo shortcut for MacOS and zooming in on points.
April 2021
  • The calculator got a new internal representation for expressions that makes nested function and variable definitions more efficient. Many cases that previously produced a “Definitions are nested too deeply” error now work.
  • Fixed bugs in the graphing calculator related to piecewise functions and range slice syntax on non-lists.
March 2021
  • The “Projector Mode” toggle in the graphing calculator has been replaced by radio buttons for default and large display sizes.
  • Improved the keyboard accessibility of draggable images in the graphing calculator.
  • The Braille mode controls in the graphing calculator and scientific calculator are now behind behind a checkbox.
  • Fixed bugs in the graphing calculator related to draggable images, label opacity, voice over accessibility for point labels on lists, and computing finite differences.
  • Fixed a bug in the scientific calculator related to decimal to fraction conversion for small decimals.
February 2021
  • Fixed bugs in the graphing calculator related to the “folder” shortcut and custom colors.
January 2021
  • Improved accuracy of pdf and cdf for the binomial, Poisson, and Student’s T distributions for large parameters.
2020

November 2020

  • You can now add custom colors to your graphs using the special functions rgb() and hsv() in the Graphing Calculator. When you assign a color expression to a variable, the color you create will appear as an option in the expression styling menu. See an example graph here.
  • The expression list in the graphing calculator is now searchable. While focused on an expression, type ctrl+ f / cmd+f to filter down to expressions that contain text matching your search string.
  • The styling menu for expressions has new options, including line width, line opacity, point size, point opacity, and label rotation. All of these attributions can be dynamic by assigning them to a variable controlled with parameters. See an example graph here.
  • Images added to the Graphing Calculator can now be configured so that they are draggable from anywhere on the image. From the styling menu on images, click the “Make Draggable” button. See an example graph here.
  • In the Graphing Calculator, we have added “smart” slider prompts that generate context-aware default bounds and step sizes for properties such as opacity and parameters in our color functions.

September 2020

  • The Graphing Calculator now supports outliers in box-plots.
  • Our homepage at www.desmos.com and our Graphing Calculator, Scientific Calculator, Four Function Calculator, and Matrix Calculator are now available in a total of 19 languages.

August 2020

  • In the graphing calculator logged in users can now attempt to recover lost work if they accidentally end a session without saving. From the menu on the left find the message “Lost work? Attempt recovery.”
  • You can now access audio trace from the built in keypad in the graphing calculator. Type an expression and look for the sound icon in the keypad at the bottom of the screen. Learn more about our accessibility features here.
  • We updated our Matrix Calculator and added it to our official list of Math Tools. Learn more.
  • New features for our Matrix Calculator - rref and trace.
  • Updates to the sound and behavior of our audio trace functionality in the graphing calculator. Learn more on our accessibility page.

July 2020

  • The graphing calculator now supports vector operations on points. Explore examples here.
  • The graphing calculator now supports integrals with infinite bounds. See an example here.
  • Added a keyboard shortcut to the Graphing Calculator to show/hide the expression list (Shift + Command/Alt + e).

June 2020

  • We released new versions of our iOS and Android graphing calculator apps
  • You can now use "arsinh(x)" as an alias for "arcsinh(x)," and similar for other related functions, which should help out our friends in the UK who use the former name for the expression. (It's still "math" and not "maths," though. We are apologetic but firm in this matter.)
  • It's Pride Month and Desmos is celebrating. Type "pride" into your graphing calculator.

May 2020

  • We added new functions to our lists: sort, shuffle, join, and filters. Read more here.
