Excellent Experience! Only suggestion is that PDFiller should offer free services to individuals and that will prompt businesses to buy your subscription just like many other online tools are offering, for example, FreeConference, GoToMeeting etc.

needed to print out applications, employment verifications and a background questionaiire that required it be typed, printed out and sent via US mail. Most online PDF's will not supply editing capabilities. Thanks PDFillier!

i am very surprised at how easy it is to retrieve and add new pdf's to my account. I originally paid for pdfiller because i wanted to send in a release of liability to the dmv. 1 year later and I am now using it for court paper work and have downloaded many forms i can fill out any time I want. Thanks. I am very happy and surprised at this application. I am glad i didn't cancel my monthly payments to pdfiller.

What an awesome product. We use accord forms so often in this office that it is nice to have help!
We like that most accord forms we use are already available from the site, but more so than that, the fact that we can upload our own documents as well. When you have to generate 150 certificates for one client, all different, this program makes that process seamless. The site runs very well, have not had to deal with freezing issues or losing extensive work because it didn't save, the site always saves my work for me. We just couldn't be more happy with the service.
There is not a lot that we do not like about the program, but one thing sticks out for sure. If one of my agents is logged on to the site and another agent logs in, the first agent will usually be kicked off. This was not really even an issue since the system always saved the agents work, and all of my agents will announce now that they are logging in.

working great so far, any difficulties are due to my lack of knowledge. My only suggestion is to hire one really dumb guy, and make it so its easy for him. Would you like me to send my resume'?

How do you calculate logarithms?
Logarithm, the exponent or power to which a base must be raised to yield a given number. Expressed mathematically, x is the logarithm of n to the base b if bx = n, in which case one writes x = logo n. For example, 23 = 8. Therefore, 3 is the logarithm of 8 to base 2, or 3 = log2 8.

How do you find the negative log?
In particular, the logarithm of a negative real number x can then be calculated as log(x)=log(|x|a)=log(|x|)+log(a)=log(|x|)+i. For all KZ. Therefore, the complex logarithm is only defined up to multiples of 2i ! Or maybe log(x)=log(|x|ei1772)=log(|x|)+log(ei1772)=log(|x|)i1772.

How do you add a negative log?
A common technique for handling negative values is to add a constant value to the data prior to applying the log transform. The transformation is therefore log(Y+a) where an is the constant. Some people like to choose a so that min(Y+a) is a very small positive number (like 0.001). Others choose a so that min(Y+a) = 1.
