(12C) Trigonometric Functions

[bshoring]

It's a wonderful program. The forensic test arcsin (arccos (arctan (tan (cos (sin (9) ) ) ) ) ) on the RPN-38 CX Simulator of the HP-38C gives me 9.000000330, which is pretty good for a financial calculator! I get that by entering 9, then
R/S X<>Y (to get SIN)
R/S (to get COS)
R/S / (to get TAN)
GTO 44 R/S (to get ATAN)
GTO 38 R/S (to get ACOS)
GTO 32 R/S (to get ASIN)

Thanks for writing it!
