HP 39g+ Graphing manual Trigonometry functions

≥	Greater than or equal to. Returns 1 if true, 0 if false.
	value1≥value2
AND	Compares value1 and value2. Returns 1 if they are both
	non-zero, otherwise returns 0.
	value1 AND value2
IFTE	If expression is true, do the trueclause; if not, do the
	falseclause.
	IFTE(expression, trueclause, falseclause)
	Example
	IFTE(X>0,X2,X3)
NOT	Returns 1 if value is zero, otherwise returns 0.
	NOT value
OR	Returns 1 if either value1 or value2 is non-zero, otherwise
	returns 0.
	value1 OR value2
XOR	Exclusive OR. Returns 1 if either value1 or value2—but
	not both of them—is non-zero, otherwise returns 0.
	value1 XOR value2

Trigonometry functions

	The trigonometry functions can also take complex
	numbers as arguments. For SIN, COS, TAN, ASIN,
	ACOS, and ATAN, see the Keyboard category.
ACOT	Arc cotangent.
	ACOT(value)
ACSC	Arc cosecant.
	ACSC(value)
ASEC	Arc secant.
	ASEC(value)
COT	Cotangent: cosx/sinx.
	COT(value)
CSC	Cosecant: 1/sinx
	CSC(value)
