Sorry, but this is crazy. If you're in physics, electrical engineering, mechanical engineering, or civil engineering[1], then trigonometry appears in so many problems - including ones that have little to do with triangles and geometry.

Calc II is heavy on trigonometry for a good reason. So many integrals that show up in the "real world" are solvable if you know your trig identities. These show up in semiconductor theory, mechanics, electromagnetics, quantum mechanics, etc.

Trig is the one thing I'm glad I was taught well in high school. Used it all the time for over a decade.

[1] And probably many other disciplines.

Trigonometry has little to do with triangles. It's more appropriately titled circleometry.

That's a clever insight. Though the measurement of circles is done using triangles, so maybe there is an even cleverer more Germanic name? Circulotrigometry.
