Motor control. If you want to have a brushless DC motor running you have to pilot 3 phases with adequate currents - and we can't use the standard 6 point drive because it is noisy.

I wouldn't say "math is useless to programmers" - rather "math is of little significance to a large number of programmers, especially those doing line of business stuff and e-commerce. I have zero use for laplace transforms or matrices or trig. I have minimal use for even basic algebra 95% of the time.
Math is a tool - like all tools, it has jobs it's fit for and jobs it's less fit for.

If you say that getting the money
is the most important thing
You will spend your life
completely wasting your time
You will be doing things
you don't like doing
In order to go on living
That is, to go on doing things
you don't like doing
Which is stupid.

Surely not useless but I don't think it deserves the emphasis it has, when I needed FFTs I learnt them, I never had a need for Laplace so I don't know it, I remember some basic trigonometry and I never had a need for something remotely as "advanced" as what we did in school.
School taught me to learn, what I learnt is largely irrelevant to me now.
If I could go back and chose to not have some math classes, I would do it

I need things much more advanced than what I did in school. From when I analyzed images in real time to find anomalies to when I wrote the algorithm to have a humanoid robot walk, up to now that I simply have to drive pumps and fans.

Yeah, sure, it's just that I don't think that since there are some programmers that make chemistry software we should all learn chemistry, same thing for maths or music for people that make DAWs.
I don't have your job  and if I did.. I would probably be of the same idea, I didn't learn CUDA at school, now I need it and learnt it, it would be absurd to think that school would have had to teach it to me.

Working in the engineering industry for 35 years I never trained formally in software or engineering but always had an interest in both even as a kid. 34 years ago I overheard my MD discussing not being able to get anyone to reprogram an inspection machine and I (stupidly?) volunteered to look at it. It was programmed by hand in binary codes which I had to decode by trial and error and a lot of intuition but got it going. I never looked back, since then my weekly routine regularly consists of 50% engineering, 50% software and 50% maths (See, I can do maths!) I consider myself as an engineer that can write software rather than a software engineer and, certainly for me, I couldn't do it without maths.

Sorry, but I find the logic of math to be great when programming.

At least it sounds as if you have one of the rare development jobs which is actually interesting.

Meh, it's producing firmware for motors... with only a single application (maybe two). It's mostly engineering the system as to lower reaction times, improve thermal and power efficiency, reduce noise and EM emissions...
Not the most interesting job I held but its perks are elsewhere (i.e. twice the pay and a third of commute distance).

And that's the reason I don't have a job like yours. 
My programming jobs have been all in the music industry, or now, banking. I use descrete maths and the occasional easy algebra.
Like golf, Calculus in all its forms are great spectator sport, but I've little interest in actually playing the game.
If you think 'goto' is evil, try writing an Assembly program without JMP.

I was once asked to do a chi-square analysis. I still don't know how to do that. Not part of statistics for physics So, I just computed averages, which were good enough to get the job done.

Riiiight, I didn't use any math in all the DSP code I wrote for embedded audio devices. Or for the IEEEish floating point package I wrote for an industrial controller language (looong time ago!). Yep, didn't need math for any of it.
About the only opinions from non-programmers I pay attention too are in regards to how an application looks and interacts with the user.

I have long said that, while I took 32 hours of college math (calculus, differential equations, and matrix algebra), I've since recycled that part of my brain to store old movie dialogue.
Much more useful.

I said "Happy 30th anniversary!" to my wife.
She replied ""6 of the happiest years of my life!"

When we were in university, my ex and I worked at the same pizza place. Cops sometimes came in. One of them, a Constable Morton, was young and fairly new on the job.
Ex: Is bestiality still against the law?
Morton: It should be! You should see some of the dogs I've gone out with!

OK, so this morning MS decides to let me update to Win 11.
So it let it, and it all goes smoothly.
A new glitch pops up with the new taskbar: you can't drag it to the side or to a different monitor in a multiple setup. Apparently the only way to move it is to change which monitor is the "main" one which means that boot problems will come up rotated 90o on my landscape monitor, and all games will play on the wrong one. No, thank you ... Another MS decision that degrades usability. 
I'll learn to live with it even though I keep trying to check the time in the wrong place.
So I'll create a Win 11 installation USB and off we go.
Nope, it decides "this PC cannot run Win 11" even though it's just upgraded to it ...
