Amplitude = 1
Amplitude is the average of how high up in the y axis something goes from the lowest point. In this case, the lowest point is -1 and the highest point is 1. So then from -1 we go to 0 then 1. that would =2. Then you would take the average so 2/2 = 1

the respond is a million. The "formula" is like this... y = A cos (x - theta), the place... A = amplitude and theta = area, or attitude. Your challenge is quite the comparable as y = a million cos (x - 0) So, A (amplitude) = a million. For greater readability, evaluate sketching a plot of cos (x) on an x-y axis. of direction, it truly is a cosine wave commencing at (0, a million), crossing the x-axis and dropping to (pi, -a million)... or (a hundred and eighty*, -a million). The wave keeps to upward thrust and fall between a million and -a million. So, that's amplitude is a million.

Amplitude is always a constant multiplied by the equation such as:
y=4sin(x)
the amplitude would be 4.
in your case, there is an implied one in front of the cosine, so the amplitude would be one.

the amplitude is 1. the standard form of a sinusoid is:
y = A cos ( wt + phi) where
A= amplitude
w = angular frequency = 2*pi*f (f = frequency)
phi = phase angle
