Returns the sine of the specified double that represents an angle.
- a
- A double containing the value of an angle measured in radians.
A double containing the value of the sine of a. If a is equal to double.NaN, double.NegativeInfinity, or double.PositiveInfinity, returns double.NaN.
Note: Multiply by pi/180 to convert degrees to radians.
The following example demonstrates using the Math.Sin(double) method.
C# Example
using System; public class MathSinExample { public static void Main() { Double d1 = Math.Sin(0); Double d2 = Math.Sin(Math.PI/2.0); Console.WriteLine("Math.Sin(0) returns {0}", d1); Console.WriteLine("Math.Sin(Math.PI/2.0) returns {0}", d2); } }The output is
Math.Sin(0) returns 0
Math.Sin(Math.PI/2.0) returns 1
