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?

@peachpi @zepdrix @rvc  :)

anonymous · Answer

like no proofs of equations, identities, or theorems.

babynini · Answer

..but what does that mean.

babynini · Answer

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??

babynini · Answer

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

anonymous · Answer

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.

babynini · Answer

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

anonymous · Answer

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
