Consider a sinusoidal coordinate system (u, w). The transformation of the coordinates cartesian (x, y) to parabolic coordinates are given by: u(x,y) = x, q(x, y) = y - a sin (bx), with a and b constants. (a) Obtaining the inverse transformation, from get the metric in the sinusoidal system. (b) Assumes that an observer moves with constant velocity v those components are v^x = v and v^y = 0. What is the speed of the observer in the system...

Change of Variables When working integrals, it is wise to choose a coordinate system that fits the problem; e.g. polar coordinates are a good choice for integrating over disks. Once we choose a coordinate system we must figure out the area form (dA) for that system. For example, when switching from rectangular to polar coordinates we must change the form of the area element from drdy to rdrd0. To determine that rdrde is the correct formula how the edges of...

8.4 The Two-Dimensional Central-Force Problem The 2D harmonic oscillator is a 2D central force problem (as discussed in TZD Many physical systems involve a particle that moves under the influence of a central force; that is, a force that always points exactly toward, or away from, a force center O. In classical mechanics a famous example of a central force is the force of the sun on a planet. In atomic physics the most obvious example is the hydrogen atom,...
