C-Sharp Asin Example – Code Sample Syntax

C-Sharp Asin Example – Code Sample Syntax

Purpose: – Illustrates using .

Purpose:
takes a double data type number that represents a sine and
returns a double value that represents the angle of that sine when
measured in radians. (you can convert the radians to degrees by
multiplying them by Math.PI/180)

Syntax:
Asin(double)

Parameters Description
double The expression represents a sine that is
to be converted into radians of an angle. Any
valid System.Double data type number between -1 and +1
if number < -1 or > 1, NaN is returned – NaN stands for Not a Number

Result Data Type Description
double represents the radians of the angle of the sine
that was specified as the input parameter.

Quick Example
Asin(0.5) // Returns .523598775598299

Step 1: Click cs to Cut-n-paste code into clsAsin.cs

        Console.WriteLine(Math.Asin(0.5)); // Returns .523598775598299
 
        //Prevent console from closing before you press enter
        Console.ReadLine();
 
    }
 
}

Step 2: Click cs to Cut-n-paste code into Module1.cs

Module Module1
 
    Sub Main()
 
 
        Dim myclsAsin As New clsAsin
        myclsAsin.Main()
 
 
 
    End Sub
 
End Module

Prerequistes:

  1. Install C-Sharp (Express or Standard Edition)
  2. Install SQL Server Express
  3. Download Northwind and pubs Database
  4. Attach Northwind Database to Databases in Sql Express
  5. Attach pubs Database to Databases in Sql Express

Notes:

  • Console Application is used to simplify things, but Windows Forms or Web Forms could also be used
  • You can build a library of syntax examples by using same project over and over and just commenting out what you do not want to execute in Module1.cs

Instructions:
C-Sharp Syntax Functions Asin

  1. Use C-Sharp 2010 Express or Standard Edition
  2. Create new project;
    • Click File/New Project
    • Select Console Application Template
    • Select C-Sharp for Language
    • name of project could be C-Sharp_Syntax.
  3. Add New folder named “Functions”
    • Right-click project name in solution explorer;
    • add new folder;
    • name of folder could be: Functions
  4. Add New subfolder named “MathFunctions”
    • Right-click Functions folder in solution explorer;
    • add new folder;
    • name of folder could be: MathFunctions
  5. Add Class Named clsAsin to MathFunctions folder
    • Right-click MathFunctions folder;
    • add new item;
    • Select class
    • Class name could be clsAsin
  6. Click on cs in code in step 1 above to copy code into clsAsin.cs
  7. Click on cs in code in step 2 above to copy code into Module1.cs
