Re: Common area of circles

I want to calculate areas. like for two circles (0, 0) and (0, 1) : the output is '1.228370' similarly my aim is to take 'n' co-ordinates, all of radius '1' and calculate the area common to all. The best I got was monte-carlo methods which is inefficient. Is there any other approach possible. On

Re: Common area of circles

I'm not sure what you're after. Are you after how to calculate the area? Or are you trying to graph it? Or an analytical solution? What do you mean by "take out the intersection"? -Xav On Thu, Feb 4, 2010 at 9:47 PM, Shashwat Anand wrote: > I wanted some general suggestion/tips only > > > On Th

Building a multiline string

Hello Maybe that's already documented, but it seems the parser accepts to build a long string w/o really using the first method: # Method1 x = "line1" + \ # cannot use comments! "line2"+ \ "line3" and instead using a list with one element like this: # Method2 x = [ "line1" # can use comments "l

Common area of circles

Given 'n' circles and the co-ordinates of their center, and the radius of all being equal i.e. 'one', How can I take out the intersection of their area. hope the picture makes it clear http://imagebin.us/images/p5qeo7hgc3547pnyrb6.gif -- http://mail.python.org/mailman/listinfo/python-list
