Sounds like youve got a nasty integral. Your going to have to integrate a polar vector in cartesian coordinates. Write the B field in cartesian and then integrate one side of the square.\n\nB.ds= miu (0) * I is true. I forget which theorem but I think its stokes theorem from vector calculus. It doesnt matter which shape you choose. The symmetry of the circle allows a simple integral because there is no dot product for the B.s since they are always parrallel. Choosing a square just makes your life horrible. If you correctly write the B field and then use the vector identity:\n\ncos theta = a.b/(|a||b|)\n\nto find the angle for the dot product you will get the same answer. It's just hard to set up the problem.\n\nIm sorry dude, good luck.

The only way to do this is by using the reduction formula for int(sin(x)^n), which is valid for n>0.  Unfortuantely, it reduces to another integral for sin(x)^(n-2), for which the reduction formula no longer is valid.  Hence, the only way to do this integral is by using numerical integration techniques.\n\nProbably the best way to do this problem is to convert sin(x)^(1/2) to a taylor series.  \n\nI did this and got:\nx^0.5 - x^2.5/12 + x^4.5/1440 - x^6.5/24192 - 67/29030400*x^8.5 .....\n\nIntegrate:\n\n(2/3)*x^(3/2)-(1/42)*x^(7/2)+(1/7920)*x^(11/2)-(1/181440)*x^(15/2)-(67/275788800)*x^(19/2)......\n\nNeedless to say, after the first 4 terms, any error from a direct integration of sqrt(sin(x) is less than 10^-6, which I would say is pretty damn close.  \n\nThere ya go...

areah of a circle=pie times r squared  (r is radius)\ndiameter= 2r\nso r= d/2\n\nso you do 6sqrt(3)  divided by 2\n(you get 3 times sqrt of 3)\nthen do that number sqared....times pie(3.14)\n(18 times pie...more accurate if use calculaterbut answer is 18x3.14......)

I think it is \nf(s)=√(pi/s)\n\nBy the way how do you do the sign for the sqrt?\nI still cant figure it out.\nI can do it in MS Word but when I copy into the the Firefox I get anything, but what I desire.\n\nIt is getting late, very late\n\nI'm running 2000. \nThank you Scott\nand \nnwohiosteve  thank you for the hint. My memory is refreshed.\npress ALT, ASCII  number , reliese ALT works

I get 8/pi as well.\ndivide up into cylinders each element 2pixsin(pix/2)dx integrate by parts gives:\n(-4cos(pix/2))+((8/pi)sin(pix/2))evaluated at 1 and zero.\nonly nonzero term is rhs at 1 which gives 8/pi.

assuming you are using a calculator, turn your calculator to degree mode or if by hand coverting from radians to degrees use this formula:\n180 degrees/pi=1 radian
