Jupyter Notebook, Latex, and Python
I've been interested in data, and how it could be applied, for a very long time.
As a result of that interest, I did some reading about data sciences, and started dabbling in Jupyter Notebook.
I played with it for a while, as part of miscellaneous personal initiatives, but my consequential use of it started when I was faced with the challenges of taking some online classes that were heavily reliant upon math, and illustrations.
During my Fundamentals of AC class, I wrote lab reports, and homework entirely in Jupyter Notebook, using custom libraries to make calculations and display graphs.

As a natural consequence of my work in Jupyter Notebook, I also developed a bit of knowledge of Latex and Markdown.
$$Z_T=X_{L_1}+X_{L_2}=0\Omega+400\Omega j+0\Omega+580\Omega j=0\Omega+980\Omega j=980\Omega\angle90°$$
$$V_{th}=V_{a'}=V_S\times\frac{L_2}{Z_T}=3V\angle0°\times\frac{580\Omega\angle90°}{980\Omega\angle90°}=3V\angle0°\times0.59\angle0°=1.78\Omega\angle0°$$
While maybe not a full skill, I have also come to love using the Schemdraw Library
