SIN(X)
Description
Sine function in radians.
Class
Elemental function.
Argument
X must be of type real or complex.
Result type/
type parameters
Same as X.
Result value
The result has a value equal to a processor-dependent approximation to sin(X).
•IfX is of type real, it is regarded as a value in radians.
•IfX is of type complex, its real part is regarded as a value in radians.
Specific forms
CDSIN, CSIN, DSIN, QSIN, ZSIN.
SIND(X)
Description
Sine function in degrees.
Class
Elemental nonstandard function.
Argument
X must be of type real.
