true....

if you can read and follow that logic, you can probably learn anything.

it actually makes sense when I became a developer.

I thought that trigonometry was the most useless thing in the world, then I needed it to animate a fucking div with CSS. CSS guys, not even a programming language. So if a thing won't never be useful for you, think that not all the people will do what you do

uh, that's last Friday for me.

Need linear algebra, trigo, calculus, geometry etc for games and AI

For developers its kinda basic stuff to make great apps

if you're not sure of where to utilize those knowledge, You can just take the wisdom from it.

by wisdom i meant refactoring certain parts of your life to make it robust and scalable (how you refactor equations, making it simpler).

seriously, thinking in maths really does help straigthen your way of thinking.

those are not trigonometry but partial derivatives differential equations (though one usually specifies boundary conditions along too). They describe many physical processes (yeah, reality is a bit more complicated besides F=ma and E=mc2). Very little use for a developer ... unless one develops finite element solvers or other scientific software which would make use of those above as test cases. Cannot say that having that knowledge will bring you a job ... the jobs for this are rare and usually in odd locations. And many of them started 30 - 40 years ago so not only you got the pleasure of maintaining a very old code base but it is usually written in Fortran. So you are not missing anything guys by not knowing those.

@PerfectExceeder my expertise is somewhat in line with what you've described and I had 3 job offers before I graduated. Fortran point is a little accurate but it's really not that bad of a language.
