We can have all of them in one equation: y = A sin(B(x + C)) + D. amplitude is A; period is 2 π /B; phase shift is C (positive is to the left) vertical shift is D; And here is how it looks on a graph: Note that we are using radians here, not degrees, and there are 2 π radians in a full rotation.

14 Μαρ 2023 · Identify the vertical and horizontal translations of sine and cosine from a graph and an equation. Calculate the amplitude and period of a sine or cosine curve. Calculate the frequency of a sine or cosine wave.
13 Φεβ 2022 · The equation of a basic sine function is \(f(x)=\sin x\). In this case \(b\), the frequency, is equal to 1 which means one cycle occurs in \(2 \pi .\) If \(b=\frac{1}{2},\) the period is \(\frac{2 \pi}{\frac{1}{2}}\) which means the period is \(4 \pi\) and the graph is stretched.
A wave is described by y = (2.05 cm) sin(kx - t), where k = 2.13 rad/m, = 3.58 rad/s, x is in meters, and t is in seconds, how do you determine the amplitude, wavelength, frequency, and speed of the wave?
Determine the time (in 50 seconds) it takes to complete one heartbeat (cycle). This is the period for this sinusoidal function. Use this period to determine the value of B. Write the formula for \(V(t)\) using the values of \(A, B, C\), and \(D\) that have been determined. Answer
Given a velocity and a period, you can imagine how far apart the peaks of the wave are. This distance is called the wavelength and is denoted by the Greek letter lambda λ. Wavelength is equal to the velocity divided by the frequency, λ = v/f.
