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…
Electrical documents, especially for learners, can contain a lot of formulas. So LaTeX with its strengths in math typesetting is a very good choice for…
In graph theory, models and drawings often consists mostly of vertices, edges, and labels. So, it may be possible, to use a simpler language for…
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…
In the Chemical formulae example we already encountered formulae for molecules. Now we like to see how to draw them. This means drawing a group…
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…
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…
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…
We will plot a sine function with PGFplots. A default pgfplots axis will be rectangular box that contains the plot. Let’s look at this. In…
