Re: USA(J)MO 2017 #3
We use barycentric coordinates. Let $P\equiv (p:q:r)$. Now, we know that $pq+qr+rp=0$ [The equation of circumcircle for equilateral triangles]. Now, $D\equiv (0:q:r), E\equiv (p:0:r), F\equiv (p:q:0)$. So, the area of $\triangle DEF$ divided by the area of $\triangle ABC$ is: $$\dfrac{1}{(p+q)(q+r)...

$$\begin{vmatrix} 2a^2 & a^2+b^2-c^2 & a^2+c^2-b^2 \\ a^2 & b^2 & c^2 \\ 0 & 1 & 1 \end{vmatrix}$$ A matrix is a simple array of numbers, they said. But a simple array on a geometry problem can cause some complex issues... DAY 1 All roles have been sent! Check out the first post for how voting ties ...

Re: BDMO Forum Mafia #2
Can you please elaborate the role of the projective preist? Suppose A is the cop, B is a basher, C is doctor and D is Projective Priest. Then, if during a night A targets D, B nightkills A, C saves A and D targets A, D will learn that B and C both targeted A and A targeted D. Note that the priest w...
