The domain of cosine is all real numbers, its range is [-1,1], and its period is 2π radians.
Cosine 0 is 1
-1<cosine<1
Cosine is 0.5
The Y-Intercept of the cosine function is X = 0, Y = cosine(0) = 1.
Period is how long it takes for the sine and cosine functions to restart repeating themselves. Both have a period of 2pi (360 degrees).
The argument of the cosine function must be (2pi/3)*x radians
The domain of cosine is all real numbers, its range is [-1,1], and its period is 2π radians.
Increase the amplitude and the frequency
Yes they are. Both have a a period of 2 pi
It is cosine*cosine*cosine.
2pi
P
It is the same period as cosine function which is 2 pi because sec x = 1/cos x
Cosine 0 is 1
y=3cos(x) peroid is 2pie
One way is to shift it to the left by a quarter of the period.
