trig--power reducing formulas
You have to use doubling formulas again to express it in terms of cos(3x). If you know about complex numbers then the derivation is easy: cos(x) = [exp(i x) + exp(-i x)]/2 cos^3(x) = 1/8 [exp(3 i x) + exp(-3 i x)+ 3 exp(ix) + 3 exp(-ix) ] = 1/4 cos(3 x) + 3/4 cos(x)

physics
(a) For the electron, E = 3.2*10^-18 J momentum = sqrt(2m*E) = 2.41*10^-24 kg m/s wavelength = h/(momentum) = 2.74*10^-10 m For the photon, the energy is the same but wavelength = h*c/(Energy) = 6.2*10^-8 m (b) Use the formulas E(photon) = h*c/(wavelength) E(electron) = (...

Chemistry
I remember that oxidation is the loss of electrons so the easiest to lose electrons will be the best reducing agent. Or the most reluctant to add electrons will be the best reducing agent. Wouldn't that be Ti? Check my thinking.
