Answer 1

yes, use a cheat sheet :P

Answer 2

heck I have several

Answer 3

Remember the following identity:
\[\sin^2 + \cos^2 = 1\]This is the most important trig identity. You can find most other identities by manipulation this one. For example, you could divide both sides of the equation by cos^2 to get this identity:
\[\tan^2 + 1 = \sec^2\]and so on

Answer 4

nice, thank you
