Famous last words of math learners before they fall off the rails in higher math:
“I don’t need to practice computations. That’s what abstraction is for.”
Sure, proofs involving eigenvalues/eigenvectors might just use Av = λv and that’s it. You might just replace A with PDP^-1 and not have to actually calculate a diagonalization.
But you know what these proofs are going to feel like if you have no experience calculating these things?
Pushing meaningless symbols around, in arbitrary patterns of allowed manipulations, without really knowing what you’re talking about.
