1. sin^2x cos^5x = (sin^2x - 2sin^4x + sin^6x) cos x -I tried to foil out the right side, but got a ton of sincos terms that I'm not sure what to do with. My teacher said it could be easier to use the left side, but I have no idea how to get to the right side from the left.
2. Solve Algebraically, 4sinx tan - 3tan x + 20 sinx -15 -My teacher left a hint, which is factor. I would normally use the quadratic formula but since there is sin and tan terms I can't do that. I don't think that there are any common terms to factor out? I need help getting started with this one.
Thank You
