Partial Differential Equations (PDEs) covers equations involving multiple variables and their partial derivatives. You'll learn about different types of PDEs, like heat and wave equations, and methods to solve them. The course dives into separation of variables, Fourier series, and boundary value problems. You'll also explore applications in physics, engineering, and finance.

Is Partial Differential Equations hard?

PDEs can be challenging, especially if you're not comfortable with multivariable calculus. The concepts are abstract and require strong mathematical intuition. That said, with consistent practice and a solid grasp of prerequisites, it's totally manageable. Many students find it rewarding once they start connecting the math to real-world applications.
