Version 3

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.
