Question

How do you find the amplitude, period, phase shift for `y=y=0.6cosx`?

Answer 1

Amplitude = 0.6, Period = `**pi**`, Phase shift = 0

Explanation:

Form for finding, Amplitude, Period, phase shift and vertical shift for cos x :
`y = a cos (bx - c) + d` and given equation is
`y = 0.6 cos x`
`**a = 0.6, b = 1, c = 0, d = 0**`

Amplitude = a = 0.6#

Period = `pi / b = pi`

Phase shift `= c/b = 0`

Vertical shift = d = 0#
