Here’s a simple problem, a lot like the problem set 6 variational calculation.
Q: [1] 5.21
Estimate the lowest eigenvalue \( \lambda \) of the differential equation
\begin{equation}\label{eqn:absolutePotentialVariation:20} \frac{d^2}{dx^2}\psi + \lr{ \lambda – \Abs{x} } \psi = 0. \end{equation}
Using \( \alpha \) variation with the trial…
