Question 744948: So I have determined that by using Leonhard Euler's formula for polygon division
T(6) = 14
T(7) = 42 and
T(8) = 132
however I am confused about how T(n) changes when you ignore distinct vertices.
Could you explain how to find T(n) while ignoring said vertices.
Note: I'm not looking for the answer but rather an explanation on how to reach the answer.
Thanks!

You can put this solution on YOUR website!
So Euler asked the following question
In how many ways can a plane convex polygon of n sides be divided into
triangles by diagonals?
and his formula is
En = 2*6*10***(4n-10) / (n-1)!
when dividing the polygon into triangles we, of course, ignore some distant vertices when we draw the diagonals......
