Trig is alright.
Disclaimer: this is not off-topic but showing some of the mathematics needed as a pilot.
It’s really about how you use your math skills as a pilot.
List of basic things taught in Trig:
This is mostly about figuring out the ratios between two sides of right triangles and being able to figure out each sides’ angle measure., which if you could infer is most likely used for calculating TOD or final approach angle (but I could be wrong).
These are the most common types of triangles of trig. So here you go. If that was a really small portion of a pilot’s mindset of mathematics, then you can figure out how much math is literally needed
