Find the areaFour circles of radius 1 cm are drawn with their centres at the four verticies of a square with side length 1 cm. Find the area, in square centimetres, of the region overlapped by all four circles. #2 20091021 00:55:16

Re: Find the areaEdit: I get the same answer as bobby except for his 1/3 multiplier. I can't see where that's coming from. Last edited by TheDude (20091021 01:10:33) Wrap it in bacon #4 20091021 01:34:52

Re: Find the areaHi; These agree with this answer although they do it in a better way. http://faculty.missouristate.edu/l/lesreid/Adv08.html http://www.askmehelpdesk.com/mathematic … 1083.html Last edited by bobbym (20091021 02:21:34) In mathematics, you don't understand things.

Re: Find the areaHi Jane;
You're not saying that her method is easier so can I presume they are of equal difficulty?
Comments like that hurt my feelings. Last edited by bobbym (20091021 17:12:25) In mathematics, you don't understand things. You just get used to them.

Re: Find the areaFun fact: If two people have different opinions, it's not necessarily true that one of them is crazy. Why did the vector cross the road? It wanted to be normal. #12 20091021 21:45:51
Re: Find the area
I wasn’t referring to you; I was referring to The moronic Dude retard before you.
Totally agree! Last edited by JaneFairfax (20091022 19:43:17) #13 20091021 22:45:32
Re: Find the area
That's a really good point. While I doubt I could have ever come up with the geometric method for solving the problem, I would have been in similar trouble if I didn't have easy access to a list of common integrals and had to integrate myself.Wrap it in bacon #14 20091021 23:21:18
Re: Find the areaHi Jane;
Was just probing to see who you were talking about, "some people", might not have meant me. Glad to see that you did mean me. I am not interested in conforming to the world's view of normalcy.
You, left out the not so... Again, no problem. I think we understand each other and I am comfortable with that, so no apology is necessary. Continue to share your viewpoints.

Re: Find the areaHi All;
Patently incorrect. Should read, whenever someone has a different opinion, quietly suspect that they are insane. Do not share this assessment with them, lest you enrage that crazy person.  Old proverb.
Those integrations if you could not have done them analytically, would have responded very well to numerical integration, to any number of digits that you require.

Re: Find the area
NonCalculus is legion. It is something similar to the argument of using computers 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.' 'God exists because Mathematics is consistent, and the devil exists because we cannot prove it' 'Who are you to judge everything?' Alokananda #17 20130621 00:08:20
Re: Find the areaThere are several books out there for doing calculus problems without using calculus. In mathematics, you don't understand things. You just get used to them.
