I Use trig and algebra all the time for construction math but I don't need to understand it to do it longhand on paper anymore.
I use a Jobber 6 calculator! The way God intended us to do trig/algebra.

That's enough to keep the buckethead coworkers away, they're allergic to math or learning!

"Camping places fix themselves in your mind as if you had spent long periods of your life in them.
You will remember a curve of your wagon track in the grass of the plain like the features of a friend."
