Abstract
A simple geometrical analysis reveals a close relation between variational methods and the WKB approximation. The procedure leads to quite accurate, analytical expressions for the discrete spectrum of quantum-mechanical models. Numerical results for the anharmonic oscillator are shown.Keywords
