Jean-Baptiste-Joseph Fourier was a French mathematician who exerted a strong influence on mathematical physics. He established the partial differential equation governing heat diffusion and solved it by using infinite series of trigonometric functions. Fourier's work provided the impetus for later work on trigonometric series and the theory of functions of a real variable. Jean Joseph Fourier was born on March 21, 1768 in ancient town of Auxurre, France. He was the ninth child of his father, Joseph …showed first 75 words of 411 total…
