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 –/2
to /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
. 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 –/
2 to /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.
