How do you convert a Riemann sum to a definite integral?
The simple answer is that we just use an infinite number of rectangles to find the area, instead of a finite number of rectangles, like we normally would when we're using a Riemann sum.
How to approximate an area with a Riemann sum?
The region between the curve and the x-axis, between x = 2 and x = 6, is shaded. We can approximate this area using Riemann sums. Let be the right Riemann sum approximation of our area using equal subdivisions (i.e. rectangles of equal width). For example, this is . You can see it's an overestimation of the actual area.
Is there a way to find the exact value of a definite integral?
Definite integrals represent the area under the curve of a function, and Riemann sums help us approximate such areas. The question remains: is there a way to find the exact value of a definite integral?
Is it possible to write the sum as an integral?
We can indeed write the sum as an integral, after research. Consider: The sum seems difficult, but really isnt. This particular sum could be solved because you had two terms ax + b and ax + c and the difference between c and b is equal to a (I think it would work in a slightly more complicated way if it was a not-too-large multiple of a).
