Sin Example Syntax C-Sharp ASP.NET | C# Sin | Source Code
Summary: – Illustrates using Sin with Source Code Syntax Example in C-Sharp ASP.NET.
Purpose:
converts an angle measured in radians to a Sin. (you can convert
the radians to degrees by multiplying them by Math.PI/180)
Syntax:
Sin(doublenumber)
Sin(doublenumber)
| Parameters | Description | doublenumber | double percision floating point number representing an angle measured in radians. |
|---|
| Result Data Type | Description | double | represents the Sin of the angle specified in parameter1. If parameter1 is equal to NaN, NegativeInfinity, or PositiveInfinity, NaN (Not a Number) is returned. |
|---|
| Quick Example | Sin(90) // Returns -0.893996663600558 |

Notes:
- You can build your own library of syntax examples by using same web site over and over and just add new web forms to it.
Instructions:
|
- Use Visual Web Developer 2010
- Create new web site;
- Click File/New Web Site
- Select ASP.NET Website Template
- Select C-Sharp for Language
- name of Web Site could be CSharp_ASPNET_Syntax.
- Add New folder named “Functions”
- Right-click project name in solution explorer;
- add new folder;
- name of folder could be: Functions
- Add New subfolder named “MathFunctions”
- Right-click Functions folder in solution explorer;
- add new folder;
- name of folder could be: MathFunctions
- Add Web Form Named Sin to MathFunctions folder
- Right-click MathFunctions folder;
- add new item;
- Select Web Form
- Check place code behind in separate file
- Web Form name could be Sin
- Click on cs in step 1 at the top of this page to copy code into code-behind Sin.aspx.cs
- Click on XML in step 2 above to copy code into web form Sin.aspx
- Right-click on Sin.aspx in solution explorer and select view in browser
