Assuming the question refers to
x(t) = 3.4*cos(5*pi*t) - pi,
the periodicity of the cos function is 2*pi
So 5*pi*t = 2*pi
or 5*t = 2
or t = 0.4
The period of the tangent function is PI. The period of y= tan(2x) is PI over the coefficient of x = PI/2
The period is 2*pi radians.
pi radians.
pi/2
2
It is 2*pi radians.
2 pi
Pi
The same as the period of y = sin x. This period is equal to (2 x pi).
Pi radians (180 degrees) is.
the answer is c, pi
The period of y=sin(x) is 2*pi, so sin(x) repeats every 2*pi units. sin(5x) repeats every 2*pi/5 units. In general, the period of y=sin(n*x) is 2*pi/n.
