The End



That’s it for Dave’s Short Trig Course. Of course, there’s a lot more to trigonometry, but there’s really no boundary between the trig and the rest of mathematics. Trig builds on geometry, uses algebra, and connects to virtually every branch of mathematics. Besides within math, trig is used throughout science, both natural science and social science; it’s used in engineering, in surveying, in architecture, and in conststruction. Computer programs use trig whenever they render or analyze images, especially three-dimensional images.

So, if you want to know more about trig, just study more math, science, engineering, etc. You’ll find it everywhere.

Thanks, and good luck with everything,
