3 cards from this section. Quick, good the night before a test.
What is the wave equation?
Think about waves in mediums like strings or air.
Name one application of the separation of variables method.
Consider musical instruments.
What does the separation of variables method help us solve?
Recall that the wave equation is a type of partial differential equation.
Is the separation of variables applicable for boundary value problems?
Think about the initial and boundary conditions.
Given a vibrating string of length L=2 meters, derive the first three mode shapes for the boundary conditions X(0) = 0 and X(2) = 0.
Recall how mode shapes derive from boundary conditions and eigenvalues.
If T(t) has a cosine term, describe its role in the temporal behavior of the wave solution.
Think about how the wave oscillates based on initial conditions.
