The exposition in this book heavily emphasizes rigour and formal-ism; however this does not necessarily mean that lectures based on this book have to proceed the same way. Jean B. Joseph Fourier was a French mathematician who proposed an idea that any periodic signal can be represented by addition of scaled basis signals of different frequencies (harmonics). The function is periodic with period 2.
