In the case of sine functions, the parent function is sin(x), and its period is 2 pi. How do you find the period of a sine wave? To find the period of a sine wave with equation f(x) = sin(Ax), use the formula Period = 2pi/|A|. If |A| = 1, then the period of the ...
frequency range of different sources. Visible light is really electromagnetic radiation, and travels as a wave across a range of higher frequencies than the waves considered so far. For example, violet light has a frequency of about f = 7.5 × 1014Hz; what is the period of the wave...
Frequency is defined as the number of waves that pass a fixed point in unit time. Learn the concepts of frequency, time period and angular frequency along with definition and formulas at BYJU'S.
The main objective of this study is to compare proportionally the incidence of total ankle arthroplasty (TAA) versus ankle arthrodesis and to determine the variables that may have influenced its indication. The secondary objective is to analyse the trend in the use of TAA using a population-based...

Now n = 4 therefore period = 1/4 = 0.25 that is 0.25 of 360 degree = 90 degree. The correct wer is B not 90degrees For sine function i.e. f(x)=sinx the period is 360 degrees Therefore for sin4x the period of sin4x when 4x=360--->x=90 d...
