ALOG(3) returns 1000
The basic trigonometric functions sine, cosine, and tangent.
SIN(value)
COS(value)
TAN(value)
Example:
TAN(45) returns 1 (degrees mode)
(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)
(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 -1 ≤ x ≤ 1.
ACOS(value)
