I'm trying to write a javascript calculation in a PDF form using cos and sin functions but I can't get javascript math functions to work.  Any suggestions?

Javascript is case-sensitive. Use Math. not math.

No, I can't get it work.

 

I tried something simple like:

 

event.value=math.cos(0);

and

event.value=math.PI

 

but it didn't return anything.  No error either, it just didn't change the cell value from the last java formula I entered that did work.

That was simple, thanks!  

 

Here's the formula I'm using for converting a magnitude and angle to the X coordinate and it works great now:

 

event.value=this.getField("Magnitude”).value*Math.cos(this.getField("Angle").value/(180/Math.PI));

What do you mean you can't get them to work?  Here's the reference.
