SIN()
Sine of the argument
- Syntax
-
- SIN (nRadiant) -> nSine
- Arguments
-
- <nRadiant> an angle size given in radiants
- Returns
-
- <nSine> the sine of <nRadiant>
- Description
-
- The function SIN() calculates the sine of an angle whose size is given in radiants (full angle equals 2*Pi - see DTOR() for angle size given in degress). A common geometric interpretation of the SIN() function is the counterkathede-hypotenuse-ratio of a right-angled triangle.
Examples
? sin (0.0) --> 0.0
? sin (1.0) --> 0.8414...
Tests
sin (0.0) == 0.0
sin (PI()/4) == sqrt(1/2)
sin (PI()/2) == 1.0
sin (PI()) == 0.0
