How do you find the frequency of a sine equation?

The equation of a basic sine function is f(x)=sinx. In this case b, the frequency, is equal to 1 which means one cycle occurs in 2π. If b=12, the period is 2π12 which means the period is 4π and the graph is stretched.

How do you find the maximum and minimum of a midline?

midline = 1 2 (max + min) = 1 2 (0.7+0.1) = 0.4. The amplitude is half the distance between the max and the min, so amplitude = 1 2 (max – min) = 1 2 (0.7 – 0.1) = 0.3. Check that these make sense.

What is the formula for phase shift?

The equation will be in the form \displaystyle y = A \cdot \cos (f (x – h)) + k where A is the amplitude, f is the frequency, h is the horizontal shift, and k is the vertical shift.

How do you know if a phase shift is positive or negative?

If b>0 , the phase shift is negative. If b<0 , the phase shift is positive. For this argument type, the horizontal stretch/shrink is applied first; this doesn’t move the original curve’s starting point. Then, the curve is shifted right/left.

What is the meaning of amplitude?

Amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path.

How do you find the frequency of a graph?

Determining wave frequency from a graph

Determining wave frequency from a graph.

How do you find the frequency of oscillation?

The number of oscillations per unit time is the frequency f. These quantities are related by f=1T f = 1 T .

What is the frequency of an oscillation?

The frequency of oscillation is the number of full oscillations in one time unit, say in a second. A pendulum that takes 0.5 seconds to make one full oscillation has a frequency of 1 oscillation per 0.5 second, or 2 oscillations per second.
