PDFfiller.com has been the most reliable and simple piece of software I have used for this type of work in a long time. Adobe has made things quite expensive and your product has been the lifesaver many times. Simple to use, end product is of high quality. That is what I was looking for and found it on PDFfiller.

I like it but felt that my "free trial" was a bit of a scam. I spent hours on a document, learning your program but was unable to print it. I don't like being "forced" into purchasing a product.

What do you like best?
This app has been immensely useful. There have been times when I am not at my desk and needed to fill out some forms and this app allowed to me to do so right on my phone. This is life saving productivity.
What do you dislike?
The only thing I disliked was the many screen you need to go through to finally start using it. Other than that, the app is great.
Recommendations to others considering the product:
It is a great app. It just takes a few minutes of patience to get through the screens.
What problems are you solving with the product? What benefits have you realized?
The business problems this app solves is the ability to conduct business anywhere. You are no longer constraint to your desk or an office. This allows for travel and connectivity almost anywhere.

I love this app I love this app, it makes sure to compensate for all the things which you would need to do for schoolwork. Personally though, I think it would make more sense to market it with ads rather than subscription. This is really useful for students who are homeschooled or aren't able to go to school and students usually don't have much in their pockets to pay for these kinds of things.

Great for PDFs! PDF filler is a great way for me to edit PDFs that clients send me. It is also very handy for finding my own PDFs that I need for a variety of reasons. I love how useful this product is. It is also really easy to use once you get the hang of it. The database of forms they have to search and use is also incredibly helpful! It can be a bit hard to use at first, especially if you aren't familiar with PDFs. I typically have to train an employee for about 30 minutes before they can really understand and use all of the features that PDFfiller provides.

I needed to send a corporate… I needed to send a corporate dissolution document to the state of Deleware and thanks to pdffiller, I was able to find the document I need, fill it in online, and even was able to mail it USPS through the site without ever having to print out a document, manually sign it and have to go to the post office to send it registered mail.

It did the work as I wanted it to… It did the work as I wanted it to provide me. I will still use it for more tasks and hopefully it stands to its reputation, functionality, and super-low to free trial time length because I am still just a student.

It is simply the product of the number and the distance between the endpoints of the section you are taking the integral of. Let the number = n. Let the starting point be a(x) and the endpoint be b(x). The area and the integral would be n*(b(x) — a(x)).
And then finish with DX to mean the slices go in the x direction (and approach zero in width). A Definite Integral has start and end values: in other words there is an interval [a, b]. We find the Definite Integral by calculating the Indefinite Integral at a, and at b, then subtracting:
Declare a variable u and substitute it into the integral: Differentiate u = 4x + 1 and isolate the x term. This gives you the differential, Du = 4dx. Substitute Du/4 for DX in the integral: Evaluate the integral: Substitute back 4x + 1 for u:
