An Elementary Treatise on Fourier's Series And Spherical, Cylindrical, And

It' s important text to start study theory of thermal flow in one or two dimension. We can find a ease application of ellipsoidal harmonics and we have many examples that help the student to understand the math problem.

Another in Dover's series of reissues of long out of print books. Here we get Byerly's masterful text on Fourier analysis. A century old. But the notation is essentially still used today. The font is old fashioned. Since partly to save costs, Dover did a photoreproduction of the original text, instead of resetting the text. Another thing to note is that there are very few graphs, as compared to a modern book. Typical of texts of its time. But numerous examples are worked out, and you can profitably go through these.
