Dummy variable integration
WebJan 7, 2015 · Dummy variables are local to the sum/integral/logical expression in which they occur. For example, knowing ∑ j = 1 n a j = ∑ k = 1 n a k or ∫ − ∞ ∞ f ( j) d j = ∫ − ∞ ∞ f ( k) d k by no means allows us to deduce that j = k: the dummy indices appear in distinct sums/integrals, outside of which they have no meaning. When you write Webx ′ is a so-call dummy variable. The integral could just as well have been U x − U x 0 = − ∫ x 0 x F x ( τ) d τ without changing the result. The variable τ is "integrated out" and the result is a function of x with x 0 as a parameter. See, for …
