I did a lot of shopping , signed up with a few other apps, once I tried this one,I went back to all the ones I was on a free trial with and cancelled . This was the one. It was easy and I was able to use it the way I wanted immediately and have been using it almost every day.

Great Customer Service
Great app, but even better customer service. I needed to cancel my membership for financial reasons, but I failed to do so before it renewed and my bank account was drafted. I submitted a request through the website for support and requested a refund. Zoe replied via email within an hour and had already issued the refund. Clearly they care about their customers, provide easy communication options and have fair policies in place.

What do you like best?
pdfFiller gives me the tools to customize forms specific to our office and our industry. I also love the ability to create templates for new documents that I design in-house. This cuts down on costs because these templates do not have to outsourced. It is all right there at my finger tips. One additional bonus specifically for me: everyone in our office knows my handwriting is difficult to translate. PDF filler gives me a fast and efficient tool to complete documents and forms in a timely manner.
What do you dislike?
What's there to dislike? It's all good.
Recommendations to others considering the product:
Give it a try for a trial use. I assure that you will not be disappointed with pdfFiller. This product will make your job much easier.
What problems are you solving with the product? What benefits have you realized?
As a contractor, we have some customers that require a specific contract form. This form requires customization for each customer. pdfFiller allows me to include the specific terms and conditions in the contract while customizing it for the specific customer. This is a huge win for our company since we would normally have to outsource this contract to be completed by others.

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.
