Re: centroids

One use of a centroid is that it tells you the location of the triangle's centre of mass, if the mass is of uniform density.

Re: centroids

Hi;

There are many, many more. For instance, the famous Fermat - Torricelli point.


In mathematics, you don't understand things. You just get used to them.
90% of mathematicians do not understand 90% of currently published mathematics.
I am willing to wager that over 75% of the new words that appeared were nothing more than spelling errors that caught on.
