[Term Entry] C# Math-functions: SinCos()

[ylevental]

Added documentation for the Math.SinCos() method which returns both the sine and cosine of a given angle as a tuple. This method is more efficient than calling Math.Sin() and Math.Cos() separately.

Resolves #7953

Description

Added documentation for the Math.SinCos() method in C# math-functions. This method returns both the sine and cosine of a given angle as a tuple, which is more efficient than calling Math.Sin() and Math.Cos() separately when both values are needed.

The documentation includes:

• Complete YAML metadata following the term entry template
• Method description and syntax
• Static example with expected output
• Runnable codebyte example

@mamtawardhani Obligatory confession: I did this in three minutes with https://claude.ai/code

The fastest ever. All I had to do was type in "Work on Issue #7953". I am in shock, now we can do dozens of issues in a single day.

Would that be okay, for this issue and future ones?
