Question:
Check your results in Problem 1.11(b) with the following “numerical experiment.” The position of the oscillator at time t is x(t) = A cos(ωt).
You might as well take ω = 1 (that sets the scale for time) and A = 1 (that sets the scale for length). Make a plot of x at 10,000 random times, and compare it with ρ(x).
In Mathematica, first define
then construct a table of positions:
and finally, make a histogram of the data:
Meanwhile, make a plot of the density function, ρ(x), and, using Show, superimpose the two.
Problem 1.11(b)
(b) Determine Δj for each j, and use Equation 1.11 to compute the standard deviation.
