Graphing points and improved solving

June 02, 2023

Editing an **expression** is now done directly in the **cell** that contains it.

The calculator is now able to plot a **list of points** in the form of `{(1,3),(2,3),(3,5)}`

. It is also possible to plot a **single point** in the form of `(1,3)`

.

You can now plot the scatterplot from the data in the **Regression** application by typing, for example `(X1,Y1)`

.

Furthermore, the **Grapher** now plots the **polar line** whose equation is in the form `θ=a`

.

When a **linear system** has infinitely many solutions, the calculator now gives the **parametrized form of the solutions**.

In the **Distributions** application, it is now possible to calculate the value of μ or σ from a Normal probability distribution.

To do this, simply leave the value to be calculated (μ or σ) blank in the second step and then enter the **value of the probability**. The calculator will then give the requested value below the graph.

The **Regression** application now automatically creates the function corresponding to the chosen model. You can find it in the **Variables** menu. This makes it possible to use the function in other applications such as the **Grapher**.

The calculator now reports the **standard deviation of residuals** in the **Stats** tab of the **Regression** application.

The **Data** tab now remembers the formula used when the user generated a column from a formula.

You can now input a **value** when viewing the **cumulative frequency plot** and jump to the point on the graph.

It is now possible to use the `numpy`

module of python. This module allows you to use **arrays** of 1 and 2 dimensions. You can now manipulate tables of numbers.

The functions available in the `numpy`

module are listed in the **Modules** section of the ** toolbox** key menu as well as in the

In addition, the `gcd()`

function has been added to the `math`

module.

This version also offers many other improvements.

The **Table** tab of the **Sequences** application now gives the possibility to display a column of the sum of the terms of the sequence.

Pressing the ** log** key now displays the

`10`

. The base number can then be easily adjusted.When you use a **trigonometric function** in radian mode and the argument appears to be in degrees, the calculator reminds you that **the angle unit** is set to radians, and vice-versa.

You can now activate **exam modes** within the **Settings** application. Learn more about exam compliance.

Finally, when the device is at **the lowest battery level**, the red battery icon in the status bar **flashes for a few seconds** to remind the user to recharge the calculator.
