When I did EE, didn't have access to any kind of computer algebra system. Have 'fond' memories of taking Laplace transform transfer functions and converting to z-transform form. Expand and then re-group and factor. Used a lot of pencil, eraser and line printer fanfold paper for doing the very basic but very tedious algebra. Youngsters today don't know how lucky.. (ties onion to belt, etc., etc.)

Did you make sproingies from the tear-off side strips of the printer paper, though? That was the best bit. :P

[segfault99]

Of course!

Was this professionally or in school? I still did this in an EE program 15 years ago and I can't imagine things have changed since then. I think kids still have to do lots of ugly math in EE classes.

Undergrad. Mid-late 1980s.

I wasn't making point about mathematics qua mathematics. Was thinking that if I were doing EE undergrad today, I'd use SageMath or Mathematica to crunch the mechanical algebraic manipulations involved in doing a z-transform.

I just recently got my Computer Engineering degree which is the modern Electronics Engineering and we had a whole class on transforms. We had to do it on paper, but that professor at Cal State LA knew what the heck she was doing. We learned it good.

No worries, as a self proclaimed youngster I didn't manage to understand Fourier in 2 days and never bothered again. Also had no other prior knowledge to algebra so maybe that's why I struggled. Never perceived algebra as useful in anything programming related, will continue to do so as most problems are solvable without it. I'll let the degree havers do all that stuff.

Image, video, and audio processing and synthesis, compression algorithms, 2D and 3D graphics and geometry, physics simulation, not to mention the entire current AI boom that's nothing but linear algebra… yeah, definitely algebra isn't useful in anything programming related.

So you're a programmer but you've never assigned a number to a variable or written any math operations? Do you just do string translations or something?

[perching_aix]

You might find LLMs to be a useful crutch for this to an extent, although it's very easy to take the wrong turn and go off into the deep end. But as long as you keep forcefully connecting it back to practical reality, you can get progress out of it. And of course, never actually make it calculate.

Have I got a video for you.
