Trigonometry is important in engineering mathematics. 8. It is formalization of important fundamental ideas. 9. The law of cosines is a very nice generalization of the Pythagorean theorem. This is not something that falls under 4. only. It does, but it is a genuinely useful problem solving tool. 10. A lot of kids ask "What is this trigonometry stuff?" 11. It is a good place to use reasoning skills with a small number of identities to remember.
One can make similar negative statements about just about any topic.
I have no right to say any of this since I have not taught trigonometry for years. However I use it every day. Don  Don Coleman  (606) 2777678 (Home) Mathematics Dept  2574802 (Office) University of Kentucky  2574078 (Fax) Lexington, KY 405060027  email: mtbb0@ms.uky.edu
