The definite integral as area
WebDec 23, 2010 · One is the question of why the definite Riemann integral gives the correct notion of "area under a curve" for a (nonnegative, Riemann integrable) function. The other, which seems to be what you're really asking, is the question of why an antiderivative evaluated at the endpoints of an interval and subtracted yields that definite integral. WebYou can use integral calculus to find the amount of cement you will need. If you are a statistician, you will need to find the area of a Gaussian curve more than once. Its equation: ƒ (x) = ae^ ( (x-b)²/-2c²). If you are counting an infinite series (which comes up a lot), the area under the curve is almost exactly the answer.
The definite integral as area
Did you know?
WebDefinite integrals represent the exact area under a given curve, and Riemann sums are used to approximate those areas. However, if we take Riemann sums with infinite rectangles of infinitely small width (using limits), we get the exact area, i.e. the definite integral! Created by Sal Khan.

WebA definite integral is the area under a curve between two fixed limits. The definite integral is represented as ∫b a f (x)dx ∫ a b f ( x) d x, where a is the lower limit and b is the upper limit, … WebProperties of Definite Integrals. We have seen that the definite integral, the limit of a Riemann sum, can be interpreted as the area under a curve (i.e., between the curve and …
WebDec 21, 2024 · The definite integral can be used to calculate net signed area, which is the area above the x-axis less the area below the x-axis. Net signed area can be positive, … WebThe definite integral gives you a SIGNED area, meaning that areas above the x-axis are positive and areas below the x-axis are negative. That is why if you integrate y=sin (x) …
