The analysis of structures, heat conduction, fluid flow, and wave propagation within civil engineering often requires solving partial differential equations (PDEs). The separation of variables technique simplifies PDEs into ordinary differential equations (ODEs), while Fourier series enable the expression of complex functions as sums of sines and cosines. This chapter covers both methodologies and their applications in engineering problems.
