Three-Dimensional Rotation Matrices
which implies that any three-dimensional rotation can be described by a counterclock-wise rotation by an angle θ about an arbitrary axis nˆ, where 0 ≤ θ ≤ π. However, if we substitute θ = π in eq. (5), we conclude that R(nˆ,π) = R(−nˆ,π), (6) which means that for …

scipp.ucsc.edu2. The spherical harmonics In obtaining the solutions to Laplace’s equation in spherical coordinates, it is traditional to introduce the spherical harmonics, Ym ℓ (θ,φ), Ym ℓ (θ,φ) = (−1)m s
Eigenvalues and eigenvectors of rotation matrices
scipp.ucsc.eduλ2 − 1 = 0, (12) which yields the eigenvalues, λ = ±1. The interpretation of this result is immediate. The matrix R(θ) when operating on a vector ~v represents a reflection of that vector through a line of reflection that passes through the origin. In the case of λ = 1 we have R(θ)~v = ~v, which means that ~v is a

scipp.ucsc.edusecond-order linear differential equation in the case where the origin is an ordinary point of eq. (1). 2. A Frobenius series solution about a regular singular point Consider the homogeneous second-order linear differential equation, x2y′′ +xA(x)y′ +B(x) = 0. (3) We can convert this into the form of eq. (1) by dividing by x2 and identifying
Taylor Series Expansions
scipp.ucsc.eduOf course, if p is a non-negative integer, then the sum in eq. (5) is finite (containing precisely p+1 nonzero terms) and therefore converges trivially for all real values of x, as expected. ∗ Otherwise, the radius of convergence of the binomial series is
Solving the Simple Harmonic Oscillator
scipp.ucsc.eduSolving the Simple Harmonic Oscillator 1. The harmonic oscillator solution: displacement as a function of time We wish to solve the equation of motion for the simple harmonic oscillator: d2x dt2 = − k m x, (1) where k is the spring constant and m is the mass of the oscillating body that is attached to the spring.
