WebFrequency and period are related inversely. A period #P# is related to the frequency #f# # P = 1/f#. Something that repeats once per second has a period of 1 s. It also have a frequency of # 1/s#.One cycle per second is given a special name Hertz (Hz). WebMay 18, 2024 · We also know that the period of the function is: (2/3)*pi This means that: sin (k* (x + (2/3)*pi) = sin (k*x) Remember that the period of the sine function is 2pi, then: k* (2/3)*pi = 2pi k/3 = 1 k = 3 Then the function is: y = sin (3x).
