    Undergrad Finding Radius of 3 Congruent Tangential Circles in Larger Circle

    Excellent, thank you! Good hint. The formula I have (that seems to work) is SmallRadius = \frac{LargeRadius \sin 60}{1 + \sin 60} If you paste the following into an html document, you can see it in action. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"...

    Undergrad Finding Radius of 3 Congruent Tangential Circles in Larger Circle

    Hello everyone! I'm trying to find out how to precisely construct three congruent circles inside a larger circle, each tangential to both the outer circle and the other two circles. For example: http://img4.imageshack.us/img4/1044/verybasicdrawing.png An image I found on the internet...

    Undergrad What is the equation for finding the magic constant of a magic square?

    Let me get something clear. I'm trying to prove that the magic constant is M_{2}\left( n \right)\; =\; \frac{n\left( n^{2}+1 \right)}{2}

    Undergrad What is the equation for finding the magic constant of a magic square?

    Yes, that's what I mean by the magic constant. Yes, I know that, but I'm trying to derive the formula from the series to prove that that is correct. BF

    Undergrad What is the equation for finding the magic constant of a magic square?

    Hey all. I'm trying to convert a series which gives me the magic constant for a magic square into an equation. How would I go about doing this? The series is: \mbox{S}=\left[ \frac{n+1}{2}+\left( n-1 \right)n \right]
