What's new in Matheass 9.0?
 Settings of 2D graphics (from February 2023)
The graphics can be moved by dragging them with the left mouse button and can be zoomed centrally with the mouse wheel.
You can zoom separately in x and y direction by dragging with both mouse buttons.The other functions of the previous context menu have been replaced by the buttons
Aspect 1:1, Center and Settings on the right side.Where possible, an area is chosen in the initial drawing where all the essential points are visible.
You can return to this setting by doubleclicking in the drawing.
The following program parts have been added:
Algebra
 Prime tuples
 In an interval [a,b], all prime twins (p,p+2), prime cousins (p,p+4), sexy primes (p,p+6) and prime triplets are determined.
 Calculating percentages
 The base value G, the percentage value W, the percentage p or p%, the growth factor q and the final value E are calculated if two independent values are entered.
 Calculation with big integers (since april 2021)
 Calculation with two big integers a and b with a maximum of 10,000 digits.
 Special straight lines in a triangle
 The program determines the equations of the perpendiculars, the bisectors of the sides, the bisectors of the angles and the heights of a triangle. In addition, the centers and radii of the circumference, the inscribed circle and the three excircles.
 Arbitrary Polygons (since november 2022)
 The sides and angles of the polygon are now also calculated and it is checked whether the polygon is convex, concave or selfintersecting.
In addition, convex polygons are checked whether they have an incircle and/or a circumcircle.  Mappings of Polygons

Displacement, straight line mirroring, point mirroring, rotation, centric stretching and shear can be applied to an ngon.
The input has been made clearer and the construction lines can be drawn in the diagram.  Tangent lines to circles (since february 2021)
 The following tangents will be calculated:
 The tangent to a circle k at a point B.
 The tangents to a circle k through a point P outside the circle
 The tangents to a circle k parallel to a straight line g
 The tangents to two circles k_{1} and k_{2}
 Distances_on_the_Sphere (since december 2021)
 Sequences and Series (since may 2021)
 The program determines the first n terms of a sequence (a_{i}) and the associated series
(sum of the sequence terms) if the first terms of the sequence and a recourse formula
a_{i}=ƒ(a_{0}, a_{1}, ... , a_{i1})
or an explicit function a_{i} = ƒ(i) are given.
The sequence of odd numbers e.g. can be defined explicitly by a_{i} = 2·i + 1 or recursively by a_{i} = a_{i1} + 2 with a_{0}=1 .  Factoring Polynomials
 The program calculates the rational zeros and the linear factorization of a polynomial.
 Transforming Polynomials
 A polynomial p(x) can be shifted or stretched in the xdirection and ydirection.
 GCD and LCM of polynomials (since february 2021)
 The greatest common divisor (GCD) and the least common multiple (LCM) of two polynomials p_{1}(x) and p_{2}(x) are determined..
 Calculus of Polynomial Functions
 The program carries out the curve discussion for polynomial function. This means that the derivatives and the antiderivative are determined, the function is examined for rational zeros, for extremes, for inflection points and for symmetry.
 Calculus of Rational Functions
 The program carries out the curve discussion for a rational function. That is, the derivatives, the definition gaps and the continuous continuation are determined. The function is examined for zeros, extrema, points of inflection: and the behavior for  x  → ∞.
 Integral Calculus (since February 2021 with arc lengths)
 Statistics
 In the statistics section, the histogram was supplemented by a box plot.
 Logistic Regression
 The program determines a curve fit for a series of measurements to the logistic function
with the parameters a_{1} = ƒ(0)·S , a_{2} = ƒ(0) , a_{3} = S  ƒ(0) , und a_{4} = k·S and the saturation limit S .  Data series from Johns Hopkins University (JHU) on the corona pandemic are attached as CSV files.
