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

Oct 20, 2017

Amplitude = 0.6, Period = $\ast \pi \ast$, Phase shift = 0

#### Explanation:

Form for finding, Amplitude, Period, phase shift and vertical shift for cos x :
$y = a \cos \left(b x - c\right) + d$ and given equation is
$y = 0.6 \cos x$
$\ast a = 0.6 , b = 1 , c = 0 , d = 0 \ast$

Amplitude = a = 0.6

Period = $\frac{\pi}{b} = \pi$

Phase shift $= \frac{c}{b} = 0$

Vertical shift = d = 0
