This software is in beta version. We do not recommend that you use it for a test or exam at this time. You can nevertheless try it on our Beta emulator or install it on your calculator by becoming a beta tester.

Plot conics and inequalities

The Functions application is now called the Grapher application and offers the ability to add expressions based on predefined templates. It is possible to add functions, equations of lines and conics, polar and parametric curves as well as inequalities.

To start graphing, all you have to do is select Add an element then press OK and choose a template. The Empty template allows you to type a freeform expression and the other templates can be modified.

Steps to add an item to the Functions app expression list

It is thus possible to draw conics, surfaces defined by inequalities, polar and parametric curves, and equations of lines.

Different types of plots

For equations of lines, the menu with the three dots to the right of the expression allows you to obtain the slope and the y-intercept.

Obtaining information of a line

For conics, the menu with the three dots to the right of the expression makes it possible to obtain the coordinates of the center, the semi-major axis, the semi-minor axis, and more.

Statistical tests and confidence intervals

The Probability application is now called the Inference application and adds the ability to perform statistical tests and calculate confidence intervals.

When you enter the app, you can choose whether you want to calculate probabilities, perform hypothesis tests, or calculate confidence intervals.

Main menu of the Probabilities application

You can perform a hypothesis tests on proportions or means. It is also possible to perform chi-square tests. Within a hypothesis test, input your parameters and statistics and quickly determine the conclusion of the test.

Using the Tests section

The Intervals section allows you to calculate confidence intervals on a proportion, a mean, a difference of two proportions and a difference of two means.

Using the Intervals section

But wait, there's more!

This version also offers many other improvements.

Physics and Chemistry constants are now available in the toolbox.

Constants in the toolbox

The toolbox now opens with the last function used.

When calculating an integral in the Grapher application, the window dynamically adapts to the interval.

The window adapts to the calculation of the integral.

It is now possible to reset the calculator from the Settings application.

Press-to-test allows you to deactivate features for class and exams.

Using the press-to-test
  • To clear the history of the Calculator application, you can press Shift then Backspace when the cursor is in the edit field.
  • Radians are now the default angle unit.
  • Units are now supported in calculations involving functions : abs(), floor(), ceil(), round() and sign()
  • The alignment of superscripts and subscripts has been changed.
  • A new examination mode for the International Baccalaureate (accessible when the country chosen is "International") is now available.
