HP Prime Graphing NW280AAABA manual Efg

efg	Sine, cosine, tangent. Inputs and outputs depend on the
	current angle format: degrees or radians.
	SIN(value)
	COS(value)
	TAN(value)
	Example:
	TAN(45) returns 1 (degrees mode)
Se(ASIN)	Arc sine: sin–1x.Output range is from –90° to 90° or –π/2
	to π/2. Inputs and outputs depend on the current angle
	format. Also accepts complex numbers.
	ASIN(value)
	Example:
	ASIN(1) returns 90 (degrees mode)
Sf(ACOS)	Arc cosine: cos–1x. Output range is from 0° to 180° or 0 to
	π. Inputs and outputs depend on the current angle format.
	Also accepts complex numbers. Output will be complex for
	values outside the normal cosine domain of –1≤ x ≤ 1 .
	ACOS(value)
	Example:
	ACOS(1) returns 0 (degrees mode)
Sg(ATAN)	Arc tangent: tan–1x. Output range is from –90° to 90° or –π/
	2 to π/2. Inputs and outputs depend on the current angle
	format. Also accepts complex numbers.
	ATAN(value)
	Example:
	ATAN(1) returns 45 (degrees mode)
j	Square. Also accepts complex numbers.
	value 2
	Example:
	182 returns 324
