What is an example of a proof? I'm allowed to take notes into my math final but it says "no proofs" what does that mean?

    like no proofs of equations, identities, or theorems.

    For example one thing I have is restricted domains for sin, tan, and cos I have law of sins with "use when you have one side, two angles. or angle, angle opposite" is that all ok??

    Basically I have formulas with notes on when to use it. so law of cosine: SAS, SSS

    yeah that sounds ok. It sounds like you can't take in a proof of the law of sines/cosines, etc. And you've probably been proving trig identities, so you can't take them in.

    k. Oh well I have like sin^2+cos^2=1 and tan^2+1=sec^2t that's not ok? o.o

    I would think those are ok since they're identities, but you couldn't show the proof of either of them. For example this is a proof of the 3rd pythag. identity |dw:1434732554823:dw|

    Ooh I see. So it's sort of like an example but to ..prove the identity xD

    Dude i'm just so paranoid that the whole test is going to be dropped because I put something I shouldn't on the notes lol D:

    right. You should be fine with equations, but stay away from anything where you're writing out steps to a specific problem

    Kk. Explanations of when to use are fine too? :) ex: "Are of triangle with theta and two sides: A=(1/2)a*b*sin(theta)"

    It's not a proof, so I guess so. You might want to run your crib sheet by your teacher.
