You don't say whether it's sine or cosine, but the format is \[y=A \cos (B \theta)\] where A is the amplitude and \[B=\frac{ 2 \pi }{ period }\]

ok lol thanks last question sorry how bout if the period is 2pi/period & the period is pi/2 what would the answer be? i keep getting different answers @peachpi
anonymous
  • anonymous
are you saying the period is 2pi or the period is pi/2?
anonymous
  • anonymous
and you're asking how to find B?
anonymous
  • anonymous
