4. A sawtooth wave is a kind of waveform that ramps upward and then drops off sharply. They are known for their use in music, specifically to create sounds with synthesizers. Wah! Often these signals are approximated with a Fourier series, like this plot shows: 1 0.8 0.6 0.4 0.2 0.5 1.5 Which quadrature method (trapezoid, Simpson's, adaptive Simpson's, or Gaussian) is the best choice for integrating a function like this (over the domain shown)? Explain your answer.
