Mathematical preliminaries.

Geometry. Vector spaces: linear combination, generators, bases, dimension, coordinates.

Linear applications: definition, eigenvalues, eigenvectors.

Analysis. Functions on Rn: limits, differentiation, integration, differential equations.

Mathematical aspects of Classical Mechanics.

vectors. Isometries. Applied vectors and systems of applied vectors. Regular curves

in E3, tangent and normal vectors, curvature. Systems of coordinates in E2 and E3.

Kinematics.

Space, time and observers: the absolute time function. Frames of reference. Absolute
