I'd say its really high school math. There are a number of concepts I use from 9th-12th grade math on a regular basis [e.g. DeMorgan's laws was in 12th grade iirc, most of the Algebra I use was also from 9th-10th grade] and I'm not in any of the niches you mentioned or any of the niches I'd consider "math heavy". I'd agree that college math is really only relevant to specific niches in the industry but I think the niches are larger than you mentioned. [e.g. Distributed systems, flight guidance]
