COS calculates in radians not degrees.

Cos20 in radians is 0.408082061813392

If you want to work in degrees I guess you need to convert degrees to radians before carrying out the calculation. 1 radian = 57.2957795 (180/pi) degrees.

Take a look at one of the examples under EZ-Script Functions called "SketchPad" - I have code on how to create a circle using Sin and Cos, if that's what you are looking for.

Otherwise, look into EZ-Script Function Syntax folder at the project named "SIN COS"

I realy appreciate your quick response.

Merci beaucoup

There are ACos and ASin as well - the math functions that ARC supports are:

. Sin() . Cos() . Tan() . Sec() . Csc() . Cot() . ASin() . ACos() . ATan() . SinH() . CosH() . TanH() . Abs() . Sqrt() . Ciel() . Floor() . Exp() . Log10() . Log() . Max() . Min() . Round() . E() . Pi()

Holy mathematics Rich! Next time I cut the birthday cake I'll be sure to use these functions! I am somewhat familiar with DJ's listed math functions ......except Floor() ?

I gess floor() and ciel() are reserved for AR Drone

Floor and Ceiling are math functions, not specifically for the drone.

This will probably explain it better than I can...

Or just run the following script I just knocked up...

Print("Floor: " + Floor($pi))
Print("Ceiling: " + Ciel($pi))

Floor () takes the decimals off ex: 1.234 will end as 1

Ciel () will add lyke if it will consider 1.234 be 1.9 + .1 = 2

Am i right?
