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]

WebExplanation: Frequency is the number of occurrences of a repeating event per unit of time. 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.
