Question

What is the period of y=-8sin((pi/2)*x)?

Answer 1

@Rydex21 Hi,

\(\huge \color{red}{\text{Welcome to Open Study}}\ddot\smile\)

y= A sin (mx+b) has the period of 2\(\pi\)/m
Using this can you find the period of
y=-8sin((pi/2)*x)

Answer 2

so it would be 4?

Answer 3

yup, thats correct!
it will be 4.

Answer 4

period must be zero

Answer 5

For wavelength is 4

Answer 6

@infauzan , wolf confirms that it is 4.

Answer 7

Wait i am sorry for this case, i think this question is about wave equation

Answer 8

no problem, 4 is correct period :)
