Ian Sneddon's "Elements of Partial Differential Equations" is a foundational, applied-mathematics text focusing on practical solution methods for PDEs rather than abstract theory. It offers comprehensive coverage of first-order equations, Charpit's method, and second-order equations like Laplace, wave, and diffusion equations. For more details, visit Dover Publications .

Sneddon is great for , but if the "delta-epsilon" style proofs get too heavy, you might want to supplement it with: and second-order equations like Laplace
