Question

write the equation that has amplitude=4 & period=pi/2

Answer 1

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
\[B=\frac{ 2 \pi }{ period }\]

Answer 2

its sin

Answer 3

@peachpi

Answer 4

it's still the same formula. Just change cos to sin

Answer 5

ok how bout if the amp was like 1/3 would A be 3? @peachpi

Answer 6

no it would be 1/3

Answer 7

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

Answer 8

are you saying the period is 2pi or the period is pi/2?

Answer 9

and you're asking how to find B?

Answer 10
