A phase portrait of a dynamical system is a geometric representation that depicts the system’s trajectories in the phase plane. In this tutorial, we will learn how to draw the phase portrait of Van Der Pol oscillator in LaTeX using TikZ and Pgfplots.
There are several methods that can be used to draw an arrow in the middle or at predefined position of a line. In this short post, we will highlight three methods and it’s up to you to choose one of them.
This tutorial is about drawing the electric field of an infinite line charge in LaTeX using TikZ. To this end, we will learn how to draw arrows in 3D coordinates, create shading and add arrows in the middle of a path.
