Trigonometry identities are so hard... I need some help proving these identities: *Oh, and I'm only in grade 11, so the identities we use are quotient identity and Pythagorean identity. sinx/(sinx + cosx) = tanx/(1 + tanx) cos^2x - sin^2x = 2cos^2x - 1 Thanks! Lucy

#1 I don't know. The idea of atoms being small hard particles is hard for anyone to explain, for example, why oxygen gas isn't hard or nitrogen gas isn't hard. #2.I would answer Democritus for this although he had no evidence to prove what he thought.
