Trigonometry - Trigonometric Graphs and Parameters

The sound waves produced by a tuning fork is represented by \(y = \sin 4t\), where \(y\) represents the loudness of the sound waves in decibel (dB) and \(t\) is the time in minutes.

  1. For the waves, state the
    1. amplitude
    2. period
  2. Sketch the graph of \(y = \sin 4t\) for \( 0 \leq t \leq \pi\), showing clearly the turning points and \(x\)-intercepts.
