What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
I had to use pdf Filler to fill out some online divorce documents, and after being initially upset at having to pay for a monthly subscription for a year to print it (very upset), I sucked it up, signed up, and have never stopped using it. Just discovered the eraser...very cool.

PDFfiller came in very handy, especially with the ability to fax. Recently, I had to complete documents on behalf of my mother after my father passed away. I was limited because she had no internet, so I purchased a portable MIFI and once I realized that I could fax with PDFfiller, this eliminated the need to spend money on faxing & postage.

Having the capability to complete my documents on line and print makes my job run more effective and efficient. When I utilize many of the same forms multiple times it is very time saving to be able to go in make the necessary changes and print. This programs saves valuable work time, and keeps me organized.

Helpful, does what I need to do. The only reason I gave it four stars is because you can't see the comments unless you are online and sometimes I am traveling to places without wifi access so it would be nice to view my downloaded documents and see the comments I attached to them.

How do you construct a Riemann sum?
To make a Riemann sum, we must choose how we're going to make our rectangles. One possible choice is to make our rectangles touch the curve with their top-left corners. This is called a left Riemann sum. The shaded area below the curve is divided into 4 rectangles of equal width.

What is the most accurate Riemann sum?
The midpoint Riemann sums is an attempt to balance these two extremes, so generally it is more accurate. The Mean Value Theorem for Integrals guarantees (for appropriate functions f) that a point c exists in [a, b] such that the area under the curve is equal to the area f(c)(BA).
Why do we use Riemann sums?
In mathematics, a Riemann sum is a certain kind of approximation of an integral by a finite sum. This approach can be used to find a numerical approximation for a definite integral even if the fundamental theorem of calculus does not make it easy to find a closed-form solution.

How does Riemann sum work?
A Riemann Sum is a method for approximating the total area underneath a curve on a graph, otherwise known as an integral. We saw that as we increased the number of intervals (and decreased the width of the rectangles) the sum of the areas of the rectangles approached the area under the curve.
