I need to write a program to calculate distance and bearing between two latitude/longitude points but it uses a mathematic formuls like sin, cos, atan, acos and so . Any body can help me please?
If you want to use a specific function you can always implement a truncated taylor series.
When you need those functions on the GUI client / webclient, look at the .NET System.Math:Sin() and System.Math.Cos() methods.
MESSAGE System.Math:Cos (45) SKIP
VIEW-AS ALERT-BOX INFO BUTTONS OK.
Unfortunately those .NET functions are not available on the TTY client or AppServer, but you could create a COM wrapper easily that would.
