WebFeb 9, 2024 · Theorem 1 is the formulation of integration under the integral sign that usually appears in elementary Calculus texts. Unfortunately, its restriction that Y Y must be compact can be quite severe for applications: e.g. integrals over (−∞,+∞) ( - ∞, + ∞) are not included. Theorem 2 below addresses this problem and others: WebMa 3/103 Winter 2024 KC Border Differentiating an integral S4–4 (Notice that for fixedx, the function θ 7→g(θ,x) is continuous at each θ; and for each fixedθ, the function x 7→g(θ,x) is continuous at each x, including x = 0.

WebMy derivation for switching the derivative and integral is as follows: $\frac{d}{dx} \int f(x,y)dy = \frac{d}{dx}\int f(a,y)+\int_a^x \frac{\partial}{\partial s}f(s,y)dsdy = \frac{d}{dx}\int \int_a^x \frac{\partial}{\partial s}f(s,y)dsdy$, WebIf we view the Riemann sums on the right as approximations to the area under the curve y = f(x) for a x b, then the sum is actually the sum of the areas of n rectangles of width t, and the crucial fact is that these converge to a limiting value (the \actual area") as n ! 1.

WebNov 26, 2024 · One of the techniques I saw used recently which I had not heard of was differentiation under the integral sign, which makes use of the fact that: $$\frac{d}{dx} \int_a^bf(x,t)dt = \int_a^b \frac{\partial}{\partial x}f(x,t)dt $$ in solving integrals. My question is, is there ever an indication that this should be used?
