How to solve integrals
Go back and watch the previous videos. What you taking when you integrate is the area of an infinite number of rectangles to approximate the area. When f (x) < 0 then area will be negative as f (x)*dx <0 assuming dx>0. Switch bound rule can be proved with some theorem, which was mention in one of the previous videos.
Oct 18, 2018 · Definition: Definite Integral. If f(x) is a function defined on an interval [a, b], the definite integral of f from a to b is given by. ∫b af(x)dx = lim n → ∞ n ∑ i = 1f(x ∗ i)Δx, provided the limit exists. If this limit exists, the function f(x) is said to be integrable on [a, b], or is an integrable function.
