posted by .

okay so in my review packet under the "calculator" section it says law of sines and law of cosines. i don't know what that means. i wikipedia-ed it but i don't understand what they are saying. Please help!

• trigonometry -

what grade are you in? i learn this around high school?

• trigonometry -

whoops. the question mark should be replaced by a period. ^.^

• trigonometry -

i'm a junior in high shcool. my reivew packet refers to my midterm review packet.
