comment Find the area inside of a equilateral triangle
@jpmc26, the title apparently refers to that part of the area of EBD that's inside ABC, ie, the intersection's area

comment On the gaps between consecutive primes
With the Zhang result and its follow-ons (in polymath8b project) the "No one has a clue how to prove anything along these lines" part of the answer may be obsolete

comment Modular Arithmetic - Find the Square Root
Perhaps “This gives us 2⋅2=4 primes” should say “This gives us 2⋅2=4 roots”. Also fix “We can firs calculate”

comment The largest possible prime gap?
@BradGraham, it isn't (eg 2*3*5-1 = 29) so I have edited to correct that error. Thanks.

comment Is the function $f( x)=1/|x|^{1/2}$ Lipschitz continuous?
The stated $x_i$ don't work; eg if C = 1+e for small positive e, $|f(x_1)-f(x_2)| < C|x_1-x_2|$. However, $x_1 = \frac{1}{C^2}$ and $x_2 = \frac{1}{2C^2}$ work.
