Hi Gintaras,

I was wondering if Trigonometry functions (sine, cosign, tan, atn) were supported in QM. I see VB6 and updated .NET versions:

http://msdn.microsoft.com/en-us/library/...s.80).aspx

I don't see a lot of use of this for me in general but for one thing I am doing, I need to draw arrowheads on lines drawn with a mouse gesture (for horizontal and vertical "swipes", it's easy) but for any other oblique angle, I need a litle trig!

I found this resource that basically tells me how to go about it but it needs the trig functions

http://www.dbp-consulting.com/tutorials/...Arrow.html

Unlike in the webpage, I am not interested necessarily in creating a general drawing function with specifiable arrowhead type/style etc., just appropriate simple line angles for my arrows reflecting the angle of the user's swipe.

Thanks,

S
