Re: [amibroker] Re: plot sin(30)=1/2

["Tomasz Janeczko" <groups@xxxxxxxxxxxxx>]

Hello,

Did you read the manual (one page regarding sin() function)?
http://www.amibroker.com/f?sin

It says:
      SYNTAX  sin( NUMBER )
      sin( ARRAY )  
      RETURNS NUMBER,
      ARRAY  
      FUNCTION  Returns the sine of NUMBER or ARRAY. This function assumes that the ARRAY values are in radians.  


Radians are not degrees.

PI = 3.1415926;
FullCircle = 2 * PI;
OneDegree = 2 * PI / 360;

30 degrees = 30 * 2 * PI / 360;

Best regards,
Tomasz Janeczko
