Exercise 1. Graph g versus (v/c).
Exercise 2. Graph L/L0 versus (v/c) for a meter stick. For what fraction of the speed of light does the moving meter stick appear to shrink to 0.5m according to a stationary observer?
Exercise 3. Graph T/T0 versus (v/c) for a second. For what fraction of the speed of light does a one second time interval according to a moving observer appear to a stationary observer to be a minute?
Symbolic computations (integrals, derivatives, algebra)
Exercise 4. Show that the spacetime interval, Ds2 = x2 + y2 + z2 - (ct)2, is invariant under a Lorentz transformation.
