Recently tried to use a function that wasn't available to me which I thought the personal plan I had subscribed to gave to me. I had a chance to do the shoppers review survey and because of this gave them three stars. I was surprised to get an email from PDF filler offering me an upgrade to my subscription so that I could get all the features that I want free for a year. It certainly resolved my issue and I was glad to upgrade my previous rating of PDF filler to 5 stars! Great customer service!

The only issue I had was I had to complete it all in one sitting. Even though I paid for the sertvice it wouldn't let me save it. I started the document 3 times and lost all previous info the first two times.

The outputs of the system are great ... just your opening page is a bit confusing. I just wanted to look convert a document but couldn't see conversion icons - finally worked out that I have to use Add New button - remember people are coming to your website from other portals they have used before - and like me they look for a document conversion tool!

This was a great program
This was a great program. I just don't use it enough to justify paying annually. I wish there was a charge per file option.

EXCELLENT Customer Service
I requested a refund on my annual subscription after it had been taken out of my account. I explained that I don't use the software, and did not need to have my subscription renewed. The person who helped me was very kind, and responded promptly. I had a full refund within 48 hours! EXCELLENT customer service!

PDFfiller immediately reached out to help me when I was having trouble navigating their site for the first time. Their agent gave me easy directions to follow, and I was able to complete my goal of converting pdfs into word documents so my students could write on them virtually.

What do you like best?
User friendly. Can do anything I really need, from editing pdfs, splitting up and saving parts of documents, signed documents, etc.
What do you dislike?
The sign in page can be a bit wonky and hard to see if you're signed in. If you've been signed out and start uploading it puts you into the trial mode, and once you figure out whats going on you have to start over.
What problems are you solving with the product? What benefits have you realized?
Signing documents is really important for me, which is the biggest benefit. But the ability to edit and fill out pdf documents has been wonderful as well.

What is the formula of integration?
f(x)DX=F(x)+C, ifF(x)=f(x). In this definition, the is called the integral symbol, f(x) is called the integral, x is called the variable of integration, DX is called the differential of the variable x, and C is called the constant of integration.
What is the basic formula of integration?
f(x)DX=F(x)+C, ifF(x)=f(x). In this definition, the is called the integral symbol, f(x) is called the integral, x is called the variable of integration, DX is called the differential of the variable x, and C is called the constant of integration.
What is formula of integration by parts?
DX = d(UV) DX = u DV DX + v Du DX. Rearranging this rule: u DV DX = d(UV) DX v Du DX. Now integrate both sides: This is the formula known as integration by parts.
What is UV rule of integration?
Integration by Parts is a special method of integration that is often useful when two functions are multiplied together, but is also helpful in other ways. You will see plenty of examples soon, but first let us see the rule: u v DX = UV DX u' (v DX) DX. u is the function u(x) v is the function v(x)
What is basic integration?
Basic integration formulas. The fundamental use of integration is as a continuous version of summing. But, paradoxically, often integrals are computed by viewing integration as essentially an inverse operation to differentiation. (That fact is the so-called Fundamental Theorem of Calculus.)
What is the upper limit of integration?
The numbers a and b are called the limits of integration with a referred to as the lower limit of integration while b is referred to as the upper limit of integration. Note that the symbol, used with the indefinite integral, is the same symbol used previously for the indefinite integral of a function.
How do you change the limit of integration?
