In C# I have this:
double Cos = Math.Cos(32.471192290848492); //Equals 0.49299653250335213
But when I do this in a calculator I get this
(0.84366148773210745476752872050588)
Why is it returning the wrong value?

C programming language is a machine-independent programming language that is mainly used to create many types of applications and operating systems such as Windows, and other complicated programs such as the Oracle database, Git, Python interpreter, and games and is considered a programming foundation in the process of ...
In the real sense it has no meaning or full form. It was developed by Dennis Ritchie and Ken Thompson at AT&T bell Lab. First, they used to call it as B language then later they made some improvement into it and renamed it as C and its superscript as C++ which was invented by Dr.
What is C? C is a general-purpose programming language created by Dennis Ritchie at the Bell Laboratories in 1972. It is a very popular language, despite being old. C is strongly associated with UNIX, as it was developed to write the UNIX operating system.
C is a general-purpose language that most programmers learn before moving on to more complex languages. From Unix and Windows to Tic Tac Toe and Photoshop, several of the most commonly used applications today have been built on C. It is easy to learn because: A simple syntax with only 32 keywords.
Math.Cos is expecting an angle in radians. I suspect your calculator is working in degrees.
You should be able to get the same answer by converting the value in degrees to radians:
double angleInDegrees = 32.471192290848492;
double cos = Math.Cos(angleInDegrees * (Math.PI / 180.0));
