Draw the following sine wave in the time domain, showing amplitude and phase:
s(t) = 3sin (2π2t + π)

Answer with Explanation:

Part 1)

The given sine wave is as

The graphical representation of the wave is shown in the attached figure:

Part 2)

For a general wave equation

'A' is defined as amplitude of the wave

is defined as phase of the wave

Upon comparing with the given wave function we observe

1) Amplitude of the given wave is 3

2) Phase of the given wave
