[PDF] x d dx operator



Mathematical & Physical CONCEPTS in quantum Mechanics

So d/dx x = 1 + x d/dx. Since A & B are operators rather than numbers they don't necessarily commute. If two operators A & B commute



The Operator $(x rac{d}{dx})^n$ and Its

Although the operator (x d)n is unfamiliar to many it has a surprising num of applications. As far back as 1740

d dx ekx = kex where k may take on any value. (2) The operator x d dx also has an infinite set of eigenfunctions xn 



OPERATORS An operator is a recipe showing how to get a function

The eigenvalue equation for d/dx is (d/dx)f(x) = ?f(x). Ob- viously any f(x) = ekx with arbitrary k is an eigenfunction of the operator
