1. Fourier series help break periodic signals into simple waves for easier analysis.


2. Fourier’s law states that heat flows from hot to cold proportional to the temperature gradient.


3. Fourier transform focuses on frequency analysis, while Laplace transform is broader and suited for solving differential systems.

1__ Fourier séries are important bé cause are used too :

Analyse waves and vibrations
Solve differntial équation
2__fourier's Law its state that thé heat flux IS proportional to thé négative température gradient
3__fourier trrnsform used to analyze thé fréquency content
Laplace transform suited for solving differntial systèmes
