1) Fourier's integral formula. f(x)=12a0+∞∑n=1{ancos(nπxL)+bnsin(nπxL)}. f ( x ) = 1 2 a 0 + ∑ n = 1 ∞ { a n cos ( n π x L ) + b n sin What is the Fourier transform in engineering math?
The Fourier transform is a mathematical method that expresses a function as the sum of sinusoidal functions (sine waves).
Fourier transforms are widely used in many fields of sciences and engineering, including image processing, quantum mechanics, crystallography, geoscience, etc.The Fourier transform is a useful tool for solving many differential equations.
As an example, consider a damped harmonic oscillator subjected to an additional driving force f(t).
This force has an arbitrary time dependence, and is not necessarily harmonic.
The equation of motion is d2xdt2+2γdxdt+ω20x(t)=f(t)m.
