Aw, but triangles and circles are such a huge part of everyday life, one should understand them well for that reason alone.

From as practical as hammering wood together to as abstract as noticing the sine curves of the seasons.

And without Pythagorous, you can't grok Euler's Identity, which would be a real shame.

Finally, trig is the gateway to Euclidian Geometry, which is the first taste of realish math most people get in High School...

Don't forget that trig pops up everywhere in more advanced math as well. Fourier/Laplace transforms anyone?
