You reached 99999 points, so you achieved position 1 on the ranking list
You type 20.000 characters per minute

THERE IS A MAJOR FLAW IN THESE FORUMS!..i see that there is a math thread!...where the *dance* is the PHYSICS THREAD?!..
anyway...Trigonometry is always the best
try this:
(a^2-b^2)/(a^2+b^2)=sin(A-B)sinC/(1+cos(A-B)cosC)
sinA+sinB+sinC=2p/2R----------where p is the semiperimeter...
