Continuous systems,The particle P is denoted by the Lagrangian coordinates.which may be interpreted as its(curvilinear)coordinates in a certain reference configuration of the body. (Unique notation, continuously differentiable → no cracks, etc.)

Methods to calculate eigenvalues of conservative systems,Separation of variables, cf. sect. 5. 1, transforms the equations of motion of section 2 into.where L and . may be matrices and U may be a vector, e. g., in sect. 2. 23.

Equations of motion for (nonlinear) nonconservative systems,Differential equations and boundary conditions can be established as in section 2. 1. Nonlinear terms arise from geometrical nonlinearities and from nonlinear constitutional equations.
