C# .Sinh()

The Math.Sinh() class method returns the hyperbolic sine of a given angle.

Syntax

Math.Sinh(angle);

The Math.Sinh() method takes only one parameter: an angle in radians of type double. The method returns the hyperbolic sine of the angle as a double value, except if the value of angle equals:

• NaN (not a number), then it returns NaN.
• NegativeInfinity, then it returns NegativeInfinity.
• PositiveInfinity, then it returns PositiveInfinity.

Note: Depending on the operating system or architecture, the exact result or the input range of the Math.Sinh() method may differ due to the differences in the C runtime environment.

Example

The following example first converts 88 degrees to radians, then uses the Math.Sinh() method to return the hyperbolic sine of that angle. Math.Round() rounds up the result to five decimals. Finally, the Console.WriteLine() function prints the result to the console:

using System;

public class Example {
  public static void Main(string[] args) {
    double degrees = 88;
    double radians = degrees * Math.PI/180;
    double hyperbolicSine = Math.Round(Math.Sinh(radians), 5);

    Console.WriteLine("The hyperbolic sine of " + degrees + " degrees is: " + hyperbolicSine);
  }
}
