SUMMARY
A "well behaved function" (WBF) in the context of physical phenomena is defined as a function that is continuous and differentiable at all points, ensuring that the gradient remains continuous. In quantum mechanics (QM), a WBF typically requires that the second derivative, u", is finite for smooth potentials, although higher derivatives may be discontinuous. For cases involving a delta function potential, a well behaved wave function can exhibit a discontinuous first derivative, highlighting the nuanced nature of WBFs in different scenarios.
