Functions and commands 103
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 –1 x. 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 –1 x. 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 .
ACOS(value)
Example:
ACOS(1) returns 0 (degrees mode)
Sg ( ATAN ) Arc tangent: tan –1 x. 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:
18
2
returns 324
