Topic:
Level: Level 2
Assessment: EX60 CW40
Requisites: Pre PHYS0008
Aims & learning objectives:
To extend further the student's familiarity with relevant analytical and statistical techniques. On completion, the student should be able to: use statistical tests of significance; analyse ex perimental data using linear regression; solve simple and partial differential equations
Content:
Differential Equations: Formulation of equations of motion (Newton's second law, pendulum, mass-spring systems); free and forced linear oscillations (undamped motion, damped motion, resonance); Fourier series (periodic functions, Euler formulas, half-range expansions); wave and diffusion equations (separation of variables, use of Fourier series ). Statistics: Elementary probability theory: conditioning, independence, distribution functions, hazard functions for failure times. Means, standard deviations. Sums of independent random variables. The Central Limit Theorem. Confidence intervals, t-distrib ution, regression. First thoughts on model validation. All topics will be illustrated via the use of a user-friendly computer package, full instructions for the use of which will be provided. A complete understanding of what the computer is doing in simpl e situations should equip the student to make judicious use of packages in more sophisticated contexts.
