I use basic math daily. I use algebra frequently.
I have not use trigonometry since I passed high school trigonometry.
Most people in modern society don't use it.
3d graphics and video games use a lot of trig
Definitely. Sometimes I wonder how hard those things would've been to program in my projects if I was never taught any of it in HS. It certainly made me grateful that I paid attention in those classes!
have you ever played a video game where you're throwing a grenade and the UI shows you where the grenade will land?
Just trying to think of the most basic uses of trig that would occur.
Without learning about how the trigonometric relationships of a throw relate to the physics of it, I don't think a person that sees no value in knowing trig, sin and cos would change their mind.
I like to view things with quantum physics in mind. "That's weird and counter-intuitive...", "I guess it's meant to be that way."
Obviously it doesn't apply to everything, and often your gut feeling is probably right. But the philosophy helps in keeping an open mind.
With trigonometry, you don't use it directly, but AC electricity and radio waves (eg WiFi or your phone) extensively rely on it.
