Web30 de sept. de 2024 · Eq 3.7. To solve the heat equation using Fourier transform, the first step is to perform Fourier transform on both sides of the following two equations — the heat equation (Eq 1.1) and its boundary condition. Reminder. … WebThis is because the heat equation takes takes the second derivative of the function and subtracts it from the function. With a normal function this would result in a long chain of subtracted derivatives but because the second derivative of a fourier coefficent is a multiple of itself (by a decimal factor) it makes it much easier to compute.
