Why is it that we use a scalar parametrization of a … WebJan 16, 2024 · In this section, we will see how to define the integral of a function (either real-valued or vector-valued) of two variables over a general path (i.e. a curve) in R2. This definition will be motivated by the physical notion of work. We will begin with real-valued functions of two variables. In physics, the intuitive idea of work is that

Webof the path integral over the usual formulation of quantum mechanics in terms of the Schr¨odinger equation. In fact, the path integral or Lagrangian formulation of quantum mechanics involves charac-teristically different modes of thinking and a different kind of intuition than those useful in the Schr¨odinger or Hamiltonian formulation.
, the line integral over some path C, is ∫ C F ⋅ d r. When expanded, this can be written as ∫ C P (x,y) dx + ∫ C Q (x,y) dy, which basically means that the line integral of this vector field is the sum of the line integral of its scalar field components, P and Q. patizWebFeb 22, 2024 · Here again, we can act as if the two variables are independent. Conclusion For a complex field (bosonic or fermionic), the path integral is an infinite product of 2 dimensional complex integrals. Whether we write : D ϕ = ∏ x d 2 ϕ ( x) or.
