2pi radians or 360 degrees
It is the same as Sine period , except that the curve is shifted by pi/2 radians ( 90 degrees)
The domain of cosine is all real numbers, its range is [-1,1], and its period is 2π radians.
Cosine (0) = 1 Sin(0) = 0 The sine and cosine curves are two intertwining curves, that complement each other, hence the words 'Sine (Curve) and Cosine ( COmplementary Curve).
-1<cosine<1
The Y-Intercept of the cosine function is X = 0, Y = cosine(0) = 1.
The cosine of 0.57 degrees is 0.999951. The cosine of 0.57 radians is 0.841901
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
Inverse of Cosine is 'ArcCos' or Cos^(-1) The reciprocal of Cosine is !/ Cosine = Secant.
y=3cos(x) peroid is 2pie
One way is to shift it to the left by a quarter of the period.
