Abstract
By using Feynman's path integral formalism in the second order for the rela tivistic Lagrangian for a spinless particle in a gauge field and applying t he covariant derivative instead of the commonly used derivative, but withou t knowing the operator expressions for the momentum and energy, one can obt ain the Klein-Gordon equation.
