F t sin 2πt /πt

WebTo find the period T, we need to find the smallest positive value of p such that f(t+p) = f(t) for all t. Using the trigonometric identities, we can rewrite f(t+p) as: f(t+p) = 2[cos(πt+πp) + cos(2πt+4πp)] - 2 = 2[cos(πt)cos(πp) - sin(πt)sin(πp) + cos(2πt)cos(4πp) - sin(2πt)sin(4πp)] - 2 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.
