Electrical trade depending on the location in the industry of Calculus or better. Most doesn't require much more than arithmetic.
If you don't work in some fields, don't speak across all fields. Engineers do math based on the job and use what they can in doing it.
My dad was into n-dimensional space at work. And he could calculate in it. After-all Over 100 years ago Maxwell worked on advanced mathematics for electronics and others.
I just completed a paper on advanced mathematics. Most of which is over
