Solving the heat equation: Differential Equations - Part 3 of 5

The video tutorial explores the heat equation, focusing on its one-dimensional case in a rod. It discusses the challenges of solving partial differential equations (PDEs), emphasizing the importance of boundary and initial conditions. Joseph Fourier's method of using sine waves to solve the heat equation is highlighted, along with the concept of expressing functions as sums of sine waves. The tutorial also covers the role of exponentials in solutions and the significance of boundary conditions. It concludes with a discussion on frequency adjustments and harmonics, setting the stage for future exploration of PDEs.
