The period of a function f f is defined to be the smallest positive value p p such that f (x+p)= f (x) f ( x + p) = f ( x) for all values x x in the domain of f f. The sine, cosine, secant, and cosecant functions have a period of 2π 2 π. Since the tangent and cotangent ...

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. http://earlemath.weebly.com/uploads/8/7/4/4/87448436/notes_key_graphing___amplitude_notes_key.pdf philip chiang net worth

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 $\frac{2\pi}{8} = \frac{\pi}{4}$.
