Finding amplitude and period of a function
WebWe're asked to determine the amplitude and the period of y equals negative 1/2 cosine of 3x. So the first thing we have to ask ourselves is, what does amplitude even refer to? … WebWhen the position is plotted versus time, it is clear that the data can be modeled by a cosine function with an amplitude A and a period T. The cosine function cos θ cos θ repeats every multiple of 2 π, 2 π, whereas the motion of the block repeats every period T. However, the function cos (2 π T t) cos (2 π T t) repeats every integer ...

WebMay 4, 2024 · Problem: Determine the amplitude and period of y = − 3cos2x. Answer Use the formula for amplitude, with a = − 3. amplitude = a = − 3 = 3 Use the formula for period, with b = 2. period = 2π b = 2π 2 = π The amplitude is 3 and the period is π. In this example, you could have found the period by looking at the graph above. WebThe wave on the string travels in the positive x -direction with a constant velocity v, and moves a distance vt in a time t. The wave function can now be defined by. y(x,t) = Asin(2π λ (x−vt)). y ( x, t) = A sin ( 2 π λ ( x − v t)). It is often convenient to rewrite this wave function in a more compact form.
WebPeriod, frequency, and amplitude are important properties of waves. As we mentioned before, the amplitude is related to the energy of a wave. The amplitude is the maximum displacement from the equilibrium position in an oscillation. The period is the time taken for one oscillation cycle. The frequency is defined as the reciprocal of the period.

WebAmplitude describes the distance from the middle of a periodic function to its local maximum. covers the range from -1 to 1. Thus, it covers a distance of 2 vertically. Half of this, or 1, gives us the amplitude of the function. It is often helpful to think of the amplitude of a periodic function as its "height". Report an Error
