Use the sliders below to set the amplitudes, phase angles, and angular velocities for each one of the two sinusoidal functions.[br][br]Check the [b]Show/Hide[/b] button to show the sum of the two functions.[br][br]Click the [b]Reset[/b] button to restart with default values.

Add two sine waves with different amplitudes, frequencies, and phase angles. What do you notice?[br][br]Add two sine waves with the same amplitude, frequency, and phase angle. What do you notice?[br] - Change the frequency and see what happens;[br] - Change the phase angle and see what happens.[br][br]Add two sine waves with the same amplitude, frequency, and opposite phase angles. What do you notice?[br][br]Add two sine waves with the same amplitude and frequency, and with phase angles that differ by 180 degree. What do you notice?
