As an electrician I use most of it. I never use continued fractions or circle theorems.

To do the math I did in college, yes. Pretty much everyday. And yes, I still fuck up.

$\lim_{x\to8} \frac{1}{x-8} = DNE$
$\lim_{x\to5} \frac{1}{x-5} = DNE$
The conditional statement is still vacuously true though.

The only thing an engineer won't use is the stupid reciprocal thingy where do the weird multiplication.

Other than that even imaginary numbers are useful

Also fuck the teacher who tried to teach us matrixes while not explaining anything about linear algebra

No need for the sign since signless infinite considers both, if it had been right or left limit then the sign would have made sense.

My teacher never asked for the sign when it could be both, he always told us to specify with both the right and left. +- is just redundant

if you're saying that your teacher said $\lim_{x\to 0} \frac{1}{x} = \infty$ is fine, then you probably misunderstood him. or he's a massive brainlet who should be fired immediately.
