Webx = 4cos(t) and y = 4sin(t) + 1 Given we require the object to start at (4,1), we can see that x(0) = 4 and y(0) = 1. Furthermore, x(t) and y(t) have periods of 2pi as required. The last trick to note is that we require the object to travel clockwise, so we need to invert t. Therefore, x(t) = 4cos(-t) and y(t) = 4sin(-t) +1: t ∈ [0, 2pi] Webx t ( ) 3 4cos( t t π π = + + determine the fundamental frequency w o and the Fourier series coefficients a k. Solution: 4S.

It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency. The period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the frequency.
