Use the sliders below to set the amplitudes, phase angles, and angular velocities for each one of the two sinusoidal functions. Check the Show/Hide button to show the sum of the two functions. Click the Reset button to restart with default values.
Add two sine waves with different amplitudes, frequencies, and phase angles. What do you notice? Add two sine waves with the same amplitude, frequency, and phase angle. What do you notice? - Change the frequency and see what happens; - Change the phase angle and see what happens. Add two sine waves with the same amplitude, frequency, and opposite phase angles. What do you notice? Add two sine waves with the same amplitude and frequency, and with phase angles that differ by 180 degree. What do you notice?
