on mouseUp
put the label of btn "myOptionMenu" into tTrigFunction
put round(the width of this card/2) into x0
put round(the height of this card/2) into y0
put 60 into Amp
set the points of grc "myCurve" to empty
wait 0 millisec -- Force a screen refresh on the Mac
repeat with i = 1 to 360--maybe with a step of 2 or 4
put i*pi/180 into tAngle
switch tTrigFunction
case "sine"
put sin(tAngle ) into y
break
case "cosine"
put cos(tAngle) into y
break
case "tangent"
if i = 90 or i = 90+180 then next repeat
put tan(tAngle ) into y
break
end switch
put round(Amp*y) into y
put i into x
put x+ x0, y+y0 into tPoint
put tPoint & cr after tPoints
--Uncomment the following to see the curve evolve
-- set the points of grc "myCurve" to tPoints
-- wait 0 millisec
end repeat
set the points of grc "myCurve" to tPoints
end mouseUp
