I have an egg drop design contest. Here are the rules: We have to drop the egg from classroom height (about 6 feet) and from gym height (about 13-15 feet). The capsule cannot weigh more than 550 grams and cannot exceed 7"x7"x7". The egg shell and the yolk have to survive. You are...

1) What kind of triangle is ABC if for his angles we have: sin[2*(alfa)]=2sin[beta]*cos[gama] 2) If acos[alfa] + bsin[alfa]=acos[beta]+b[sin[beta] , prove that sin(alfa+beta)=2ab/(a^2+b^2)

Prove that the triangle ABC is: a) acute, if and only if tan(alfa)*tan(beta)>1 b) right, if and only if tan(alfa)*tan(beta)=1 c) obtuse, if and only if tan(alfa)*tan(beta)<1

sin^8(x) + cos^8(x) = 97 / 128
