Button at the bottom left: btnSinProgr:
Sine (of the angle [°] input) ° +- > / less than 90° possible, up to a maximum of 180°: +- only applies to programming by author Huber >90° to 180°: Enter in the text field 'Enter Number 1'!

Button at the bottom right: btnArcSinProgr:
ArcSinus (of the angle [number] input) Number +- > / less than 1,000 possible, up to a maximum of 2,000: +- only applies to programming by author Huber >90° to 180°: Enter in text field 'Enter Number 1'! [°] "

Statement about these two buttons:
These two buttons and the programming behind them were created by the author Huber for programming.

This is for the following reason:
The sine of an angle is only defined up to 90° - it is 1.00 - at a larger angle the sine becomes smaller than 1.00.
When reversing (when the ArcSine is then calculated from this) the angle becomes smaller than 90°.
However, this is incorrect for programming, as the vector then rotates against the original direction (rotates back) and therefore does not continue to rotate beyond 90° while maintaining the original direction of rotation.
An angle greater than 180° was not considered for this author's vector programming (momentum diagram) - was not necessary for this topic.

In a graphic diagram, however, the sine or the angle can be calculated for a vector rotation (impulse diagram in a traffic accident reconstruction) of more than 90° - up to 180° - the sine or the arc sine can be calculated:
In the programming program “Microsoft Visual Basic 2008 Express Edition” used by the author, a separate program had to be found because in this program the program stated “not defined” at an angle greater than 90° and no further calculations were carried out.

This wasn't a problem in the Microsoft Excel program - it calculated correctly for an angle larger than 90°.
