WebbThe number of hours of daylight H in a certain area is approximately given by the function H(t) = 2.5 cos[ b(t - d) ] + 11.5 where H is in hours and t in days, and the function has a period of one year (365 days). a) Find b (b > 0) and d if H is maximum on June 21st (month of February has 28 days). WebbThe period of a function is the distance over which the function repeats itself. In a basic sine function, this is $2\pi$. In a transformed sine function, it is equal to $2\pi$ divided by the coefficient of the angle. Here, the angle is multiplied by $8$, so the period of the function is $\frac{2\pi}{8} = \frac{\pi}{4}$.

The sinusoidal function is periodic, meaning its graph contains a basic shape that repeats over and over indefinitely.
WebbIV. Periodicity of the complex sine function. The minimal period of the complex sine function is 2…. Proof. We know that the complex sine function has period 2… (because of the 2…i period-icity of the complex exponential). The important assertion here is that if, for some complex number fi, (3) sin(z +fi) = sinz for all z 2 C; http://mathlake.com/Period-of-a-Function
WebbThe period, T of a wave is found by measuring the distance between two consecutive peaks or troughs. If a periodic function has a period of 2, then f (t) = f ( t + 2) = f ( t + 4) = f ( t + 6) This means that adding one period, T, to the value of t doesn’t change the outcome.
WebbA midline of a sinusoidal function is the horizontal center line about which the function oscillates above and below.
