That’s from my German blog TikZ.de. Recently I played with the sine function, that “wave” that everybody knows in cartesian coordinates. Let’s take a look at a 3d polar complex sine made plot. In polar coordinates the sine function is… Continue Reading →
That plot is from my German blog TikZ.de. I planned to model this nice cake: (Foto by Guido Draheim). Like a cruller, just, ehm, more digital and mathematical. How do we draw it? Let’s think of a cross-section. In polar… Continue Reading →

Over the years I created a number of LaTeX packages some of which do keep me me quite busy and have gained a solid user base. Some I wish I’d never created, but well… Other packages have their place but… Continue Reading →
For some time I looked for a way to simplify the process of linking LaTeX files of my manuscripts with the replies to editors and referees. In particular, I was looking for a way to automatically update cross-references (i.e. to… Continue Reading →
Here I fill the space below the function z = x^2+y^2 to get a solid object. I did it by: Plotting the curves at the edges, for x=0 and y=0 Plotting the bottom edges Naming the paths above using name… Continue Reading →
The sine function is a well known periodic function. Choose an argument factor, which doesn’t divide the period well, and you can see a complicated path around the origin. This plot was originally made for my blog post on TikZ.de:… Continue Reading →
The sine function is a well known periodic function. Choose an argument factor, which doesn’t divide the period well, and add another sine function with a different factor, and you can see a complicated path around the origin. This plot… Continue Reading →
This is a picture of a Julia set, named after the French mathematician Gaston Julia. Computing requires a lot of iterations, that’s why we use Lua. The function for the set is z -> z^2 – 0.742 + 0.1i. The… Continue Reading →
The Mandelbrot consists of points whose boundary is a two-dimensional fractal shape. It is named after the mathematician Benoit Mandelbrot. It’s computed using a lot of iterations, that’s why we use Lua here for the calculation. The sampling is done… Continue Reading →
With pgfplots 1.10 and its fillbetween library we can fill the area between curves in a new convenient way: draw the first function and give it a name draw the second function and name it too add a fill between… Continue Reading →
We know for example informational or scientific posters seen at conferences or at walls in universities or institutes. They mostly have certain characteristics in common: They have a large size, such as A2, A1 or even A0. People may look… Continue Reading →
Functions with two arguments can be visualized in three-dimensional plots. Getting this on paper or into a PDF, is a bit more challenging. We need a projection, a view point, or angle, there’s a depth which means parts should be… Continue Reading →
A well-known classic field of mathematics is geometry. You may know Euclidean geometry from school, with constructions by compass and ruler. Math teachers may be very interested in drawing geometry constructions and explanations. Underlying constructions can help us with general… Continue Reading →
Using basic TikZ function it’s not too hard to create a line, add some ticks and date values and annotations. This example shows another colorful predesigned way using the timeline library. Until the timelime library becomes official part of TikZ… Continue Reading →
A mind map visualizes information or ideas. Usually, there’s a main concept in the center and major concepts branching outward from it. Smaller ideas start from the major concepts. So, a mind map can look like a spider web. Here,… Continue Reading →
