How do you graph and list the amplitude, period, phase shift for #y=1/4sin2x#?
no phase shift
Consider the equation
the a value is the amplitude.
In your function, the a value is
the next value is the b value. To find the period from the b value you would use the equation
the next value is c or the horizontal translation (aka phase shift)
the c value is just 0 so there is no phase shift.
Also the d value is vertical translation in case that is useful.
