tan(x)
1 + cos(2x)
1 ^ cos(2x)
sin(2x)
Trigonometry command list-
Expands expressions of the form Exp(ria;), sin(rzx), and
cos(«n'), where n is an integer. It applies the following
substitutions:
X + y
X y
e -X e e
\ n { x y ) -X ln(x) + h \ { y )
sin(x + y) -> sin(x)cos(
2/) + sin(y)cos(x)
cos(x + y ) ^ cos(x)cos(i/) - sin(x)sin(y)
Trigonometry command list—0011)
