The Fourier series for the Odd Square Wave with period T and amplitude A is: fosd square() = A · Eo -sin 2a2n+1)* 1. Write out the first three terms of this series. 2. Use this series to find the Fourier series for an even triangle wave with period T. Don't worry especially about the amplitude this wave; let it be whatever seems most natural. Your answer must be expressed in sines, cosines, or both, with zero explic phase shift. 3. Sketch the exact triangle wave. Sketch roughly how the series would look if it included only the first few terms, and describe briefly. Write your response in such a way that it shows evidence that you have actually seen this series plotted with a computer.

Question
The Fourier series for the Odd Square Wave with period T and amplitude A is:
2a(2n+1)
fodd square(1) = A E
Sin
1. Write out the first three terms of this series.
2. Use this series to find the Fourier series for an even triangle wave with period T. Don't worry especially about the amplitude of
this wave; let it be whatever seems most natural. Your answer must be expressed in sines, cosines, or both, with zero explicit
phase shift.
3. Sketch the exact triangle wave. Sketch roughly how the series would look if it included only the first few terms, and describe it
briefly. Write your response in such a way that it shows evidence that you have actually seen this series plotted with a
