Trigonometric Functions in C#

Trignometric Functions in C# include, ACos, ASin, Sin, Cos, Tan, etc. It comes under the Math type of the System namespace.

The following is an example showing how to implement trigonometric functions in C# −

Example

 Live Demo

using System; class Program {    static void Main() {       Console.WriteLine(Math.Acos(0));       Console.WriteLine(Math.Cos(2));       Console.WriteLine(Math.Asin(0.2));       Console.WriteLine(Math.Sin(2));       Console.WriteLine(Math.Atan(-5));       Console.WriteLine(Math.Tan(1));    } }

Output

1.5707963267949 -0.416146836547142 0.201357920790331 0.909297426825682 -1.37340076694502 1.5574077246549

Above we saw the Inverse Sine value using Asin −

Math.Asin(0.2)

With that, we also saw the Inverse Cosine value using Acos −

Math.Acos(0)

In the same way, we found out the value of Tan(1), Atab(-5), Sin(2) and Cos(2).
