When analyzing a function via a method he names, one often encounters (*) discontinuities known as the Gibbs phenomenon.
A useful technique named for this man exploits the orthogonality of trigonometric functions and is used to reduce integrals of such functions to the Kronecker delta function, this man's ‘trick'. A modulus named after this man is defined as the ratio of the rate of heat conduction and the rate of heat energy storage. When analyzing a function via a method he names, one often encounters (*) discontinuities known as the Gibbs phenomenon. Known for creating a transform used to go from the time to frequency domain, for 10 points, identify this 19th century physicist whose eponymous series can express any periodic function as a linear combination of sines and cosines.
