## Improved Sequences application

• It is now possible to define linked sequences: the terms that can be used are in the Toolbox.
• Addition of the choice of the index of the first term of the sequence in the settings of the sequence.

## Improved Functions application

• New Calculus menu accessible by pressing OK when the cursor is on a curve.
• Determine the minimum or maximum.
• Determine the zeros.
• Determine the points of intersection.
• Calculate an integral.
• Determine the equation of the tangent line.
• Modification of the cursor graphics.
• Improved graphics of the graph window.

## Improved Python application

• Random module. Les following functions have been added to the Toolbox : `getrandbits`, `seed`, `randrange`, `randint`, `choice`, `random`, `uniform`.
• Addition of `input()`, `min()`, `max()`, `list[m:n]`, and the `'` character.

## Improved Probability application

• All results can now be selected and copied.
• Increased accuracy of results.
• Text fields are now dynamic and fit the text they contain.
• Use of the error function and the inverse error function for the normal distribution.

## New functions in the Toolbox

• `factor(n)` : decomposition into prime factors.
• `random()` : random number between 0 and 1.
• `randint(a,b)` : random integer between a and b.

## Improved Calculations application

• Development of the powers of multinomials `(a+b+c+…)^n`.
• The symbol `Ans` is now replaced with its exact mathematical expression.
• Simplification of logarithms to base a.
• Adding the equal sign between an expression and its exact decimal value in the results.

## And also...

• Corrected the alignment of exponents.
• Fixed a bug in setting the number of significant digits.
• Fixed a bug in `inverse(x)`.
• Improved the performance of the calculator.
• Fixed a bug on the derivative of the absolute value, improved the calculation of the derivative.
• On the Home menu, pressing the Home key or the Back key brings the selection to the Calculations application.
