Function Names
sin, sin deg, cos, cos deg, tan, tan deg, asin, asin deg, acos, acos deg, atan, atan degDescription
All common trigonometric functions are supported. All function names ending with deg use angles measured in degrees and not in radians.
In case the input value is not valid for a particular function, e.g. atan(2), or results into infinite values, then void values
will be returned accordingly.
Non-numeric values (including dates) are passed through without modifications. This is particularly suitable in combination with vectorization in order
to pass through blank contents, explanatory text, etc.
Vectorization: This function supports vectorization in the 1st function parameter.
Instead of providing a single value, you can provide a set or even a nested set which contain multiple values.
The function will then process every value and its return value contains a corresponding set containing all results.

Examples
pi[] = asin(1)*2;
echo( "Pi: ", pi[] );
echo( cos( pi[] / 4 ) ); // 45 deg.
echo( sin deg( 30 ) ); // 30 deg.
echo( asin deg( 1 ) ); // 90 deg.
echo( sin deg( { 0, 15, 30, 45, 60, 90 } ) ); // Vectorization
echo( asin( 2 ) ); // Invalid valueOutput
