Analytic Geometry
Stochastics
Alternating Current Using RLC
Affine Transformations
Triangles
Functional Graphs
This app shows objects of analytic geometry in a rotatable 3d coordinate system. You may choose between point, line, vector, angle or plane and in addition there are solid bodies like sphere, pyramid, cone, cylinder and torus.
For several combinations you may calculate the intersection or distance.
There also exists a version for Win 10 here! (external link)
This app covers the following themes of stochastics:
Binomial distribution, normal distribution, testing of hypothesis, risks of 1. and 2. kind, confidence intervals, probability
tree.
All results are also shown graphically.
There exists a Win-10 version with additional modules like 1d- and 2d-statistics, playing dice, urn models.

The program Alternating Currnet With R-L-C is designed to visualize the interrelations of electric currents and voltages in circuits using resistors, capacitors and inductors. The total voltage is assumed to be of cosine form. The main focus is on graphical representation and calculation. The following views are part of the program:
There is a similar app for Win-10
here (external link).
You may show the graphs of functions of one variable as well as those of functions in parametric form.
Tangents and integrals can be calculated an shown. In addition the calculation of intersections is available.
A much more comprehensive Win-10 programme of mine with dynamic 2d-geometry is available here (external link) for download.
This app offers affine transformatioins of polygons, points and vectors, especially
- reflection relative to a point
- reflection relative to a straight line
- translation
- rotation
- scaling
- shear
- gereral affine transformation
The capabilities of this app are also included in the Win-10 app "2D-Graphs and 2D-Geometry".
Here (external link) it may be downloaded.
This app offers to construct a triangle via the congruence sentences, calculates all sides and angles and shows the triangle in a coordinate system.
As an option, the points can be specified by their coordinates.
You may choose between the following objects:
- mid perpendicular
- median
- bisectrix of angle
- incircle
- circumcircle
- Thales circle
- square over sides
All content of this app is also available in the above mentioned Win-10 programme with dynamic 2d-geometry.
