Sine wave fit amplitude, frequency, and phase

\( y(t)=A \sin{\left(\omega t + \phi\right)} \), fit to data.
Reload several times for random data to fit.

Questions

1. Determine the effects of the amplitude \( A \), frequency \( \omega \), and phase \( \phi \).
2. How can you represent the waveform \( \cos(2\pi t) \)?
