Find the solution to the initial value problem: x(0)-0x(O)--1 x(t) write x(t) as a product of a sine and a cosine, one with the beat (slow) frequency (μ-2)/2 , and the other with the carrier (fast) frequency (μ+ 2)/2 x(t) The solution x(t) is really a function of two variables t and μ . Compute the limit of x(t씨 as μ approaches 2 (your answer should be a function of t. lim x(t,H) Define y(t)-lim x(t,u) What differential...

Extra problem 2: A lot of the math below is in Griffith's with slightly different notation. I'm asking you to do this because this is probably the single most important quantum mechanics problem ever: this is the one that started it all! In class, we found that the dimensionless radial equation for the Hydrogen atom could be reduced to A. Simplify the equation for the limit ρ → 0 and find the corresponding limiting solution. This is a second order...
