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
