MathF.Cos() Method in C# with Examples
MathF.Cos(Single) is an inbuilt MathF class method which returns the cosine of a given float value argument(specified angle).
Syntax: public static float Cos (float x);
Here, x is the angle(measured in radian) whose cosine is to be returned and the type of this parameter is System.Single.
Return Value: This method will return the cosine of x of type System.Single. If x is equal to NegativeInfinity, PositiveInfinity, or NaN, then this method returns NaN.
Below are the programs to illustrate the use of the above-discussed method:
