## 13.1: Introduction to Trigonometric

- MACSYMA has many Trig functions defined. Not all Trig
identities are programmed, but it is possible for the user to add many
of them using the pattern matching capabilities of the system. The
Trig functions defined in MACSYMA are: ACOS, ACOSH, ACOT, ACOTH, ACSC,
ACSCH, ASEC, ASECH, ASIN, ASINH, ATAN, ATANH, COS, COSH, COT, COTH,
CSC, CSCH, SEC, SECH, SIN, SINH, TAN, and TANH. There are a number of
commands especially for handling Trig functions, see TRIGEXPAND,
TRIGREDUCE, and the switch TRIGSIGN. Two SHARE packages extend the
simplification rules built into MACSYMA, NTRIG and ATRIG1. Do
DESCRIBE(cmd) for details.
