Python allows free creation of plots, unlike expensive, stagnant graphing calculators. Import NumPy and Matplotlib for basic linear and polynomial plots in Python. Seaborn lets you make statistical ...

Most linear algebra courses start by considering how to solve a system of linear equations. \[ \begin{align} a_{0,0}x_0 + a_{0,1}x_0 + \cdots a_{0,n-1}x_0 & = b_0 ...

Algebra is the bane of many a student, but it is surprisingly useful when it comes to electronics. Sure, you can just memorize all the permutations of things like Ohm’s law. But it is better if you ...

for some invertible matrix P and some diagonal matrix D. A beautiful result in linear algebra is that such a decomposition is possible if A has n linearly independent eigenvectors. Moreover, the ...

I've always liked the idea of math, but doing it by hand has been another matter. My mental CPU seems to go to 100% during hand calculation. Hand calculators are good but Python libraries are even ...
