I love being able to fill out forms that I wouldn't be able to normally. My handwriting can be hard to read and this makes it clean and clear. The others parties like it too! :)

I have been using this program for almost 2 years now and it is amazing! I have uploaded all of my work documents/forms so I no longer have to hand write every single thing. Not to mention I am saving money by not having to purchase any paper and more importantly I don't have to purchase any printer ink.

I really like the program; however, when I save I get logged out. I have not been successful at using any form except the Offer to Purchase. I need addendums.

I own a few franchise restaurants and have to use this product about once a week and it makes my time with documents way faster and easier. I don't have to download a document, scan it, sign it, and then rescan it and then send it. I can do it all electronically thanks the PDFfiller.

Interesting product the pdfFiller. I would like to learn what else I can do with this software. The new look for the PDF is wonderful but I don't know if I would be able to use the old PDF from Microsoft. It seems I just paid my Microsoft subscription. It seems that the PDF is a software of it's own and doesn't come with the Microsoft Tools.

i app works well once you find the form you need. I'm having a problem creating new forms or updating existing ones with new information while saving the old ones.

Professional look!
Got to know about PDFfiller because we use Salesforce at work, and these two are compatible. Taken together - tremendous time savings, at least several hours a week, i'd say!
Longer contracts might need a while to get fully visible on the screen, but no rush here

How do you create a Riemann sum?

What do I represent in Riemann sum?
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.
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).
How do you know if a Riemann sum is overestimate or underestimate?
If the graph is increasing on the interval, then the left-sum is an underestimate of the actual value and the right-sum is an overestimate. If the curve is decreasing then the right-sums are underestimates and the left-sums are overestimates.
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.
Why is the midpoint method more accurate?
The advantage of the midpoint method is that one obtains the same elasticity between two price points whether there is a price increase or decrease. This is because the formula uses the same base for both cases.
