Webt = [2π − π/5] / ω = 4.2518 s. (iv) At minimum amplitude, x = −4, so we have −4 = 4cos(ωt + π/5) . Dividing through by 4, we get −1 = cos(ωt + π/5) . Taking the inverse of both sides, the solution is ωt + π/5 = cos−1(−1) , and thus, t = [cos−1(−1) − π/5] / ω . http://faculty.up.edu/wootton/Calc3/Section14.3.pdf

http://linux.engrcs.com/courses/engr253/problems/SSFch3.pdf 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.
