I have a masters degree and I don’t know trigonometry.
My high school required algebra 1 and algebra 2. I took them and avoided any other math classes.
My college required college algebra classes, basically no different than algebra 1 and algebra 2. I also had to do a statistics course and a logic course.
In grad school I had to do another statistics course which was basically the same thing as the one I took as an undergraduate.
There was no point at which I had to learn trig or calculus or precalc or anything with any degree of difficulty or complexity. Those maths are widely irrelevant to my chosen career path and I’m not convinced that it’s of any value for me to return to the topics in my spare time. Since you have taken such classes, any special life insight you gained from it? If not, I just don’t see myself trying it.
