Question

Which of the following functions has a period of 4 π ?

y = sin 1/4x
y = sin 1/2x
y = sin2x
y = sin4x

Answer 1

HI!!

Answer 2

the period of \[\sin(bx)\] is \[\frac{2\pi}{b}\]

Answer 3

so not the first one
there \(b=\frac{1}{4}\) and \[\frac{2\pi}{\frac{1}{4}}=2\pi\times 4=8\pi\]
try the second one

Answer 4

i got 4n so this would be my anwser

Answer 5

im i right
