H, I missed the class so may be asking something really dumb her but have got a test today and want to do well so here goes:
in what cases should you use either of these formulas? (we have been told to remember them but not told when either is more relavent that the other, and my book doesn't say either):
s = A cos 2 pi ft
s = A sin 2 pi ft
Again sorry if I am asking a rediculous question, but better to be safe than sorry. Also thanks in advance for any help given.
