## Poster with TikZ

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:…

## Plotting in three dimensions

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…

## Releux triangle

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…

## Commutative diagram

Commutative diagrams can become complicated. They can have many columns, many rows, and a lot of arrow and labels. In such cases, for loops and…

## Simple commutative diagram

In algebra, especially in category theory, we use so called commutative diagrams. Vertices denote objects such as groups or modules. Arrows represent morphisms, which are…

## Highlighting in a formula

In a complex formula or equation, it can be useful to emphasize a specific part. We can achieve this, for example, through highlighting by color…

## Distraction-free plotting in three dimensions

We will use pgfplots for a three-dimensional plot of an exponential function. We will apply a style for reduced and shifted axes, to get a…

## Plotting in polar coordinates

The standard pgfplots axis environment is used for Cartesian coordinates. However, pgfplots provides also logarithmic axes and polar axes. Functions can also be defined in…

## Plotting a function with minimal axes

We plot a sine function with PGFplots, similar to: http://latex-cookbook.net/cookbook/examples/grid-plot/ While a grid and a lot of ticks can be useful to inspect specific values…
