Variation der Konstanten — Die Variation der Konstanten ist ein Verfahren aus der Theorie linearer gewöhnlicher Differentialgleichungen zur Bestimmung einer speziellen Lösung eines inhomogenen linearen Differentialgleichungssystems erster Ordnung bzw. einer inhomogenen… … Deutsch Wikipedia
Variation of parameters — In mathematics, variation of parameters, also known as variation of constants, is a general method to solve inhomogeneous linear ordinary differential equations. It was developed by Joseph Louis Lagrange[citation needed]. For first order… … Wikipedia
Bounded variation — In mathematical analysis, a function of bounded variation refers to a real valued function whose total variation is bounded (finite): the graph of a function having this property is well behaved in a precise sense. For a continuous function of a… … Wikipedia
Total variation — As the green ball travels on the graph of the given function, the length of the path travelled by that ball s projection on the y axis, shown as a red ball, is the total variation of the function. In mathematics, the total variation identifies… … Wikipedia
