PLEASE FIX YOUR PRICING PAGE MAKE IT CLEAR THAT MONTHLY SUBSCRIPTION IS AVAILABLE ONLY IN THE MONTHLY PRICING PAGE NOT COMBINED WITH THE ANNUAL PRICING PAGE IT MAY GET CONFUSING FOR CUSTOMERS!

No issues once I contacted the support department who answered my questions. I understand that you are in business to make money on a service. I just felt it was costly for a piece of paper or two that would cost me 10. Cents at a FedEx or Office Max type business.

Great for my online classes!
This has been a great tool for editing PDFs for my Anatomy class. The only problem is the "drawing" tool does not provide enough color options. It's very limited.

This has been a very pleasant surprise as I am a avid &somewhat devoted Adobe Acrobat user &didn't think that there existed any other app that could even come anyway close in performance, features &value to what has long been the industry standard for me...They created PDF file format..but PDFfiller has made working with them much more user-friendly &intuitive. Using the two in tandem has been both very eye-Opening ,&productive!!!

I liked their services
I liked their services, but didn't need them long term. I had thought that I had canceled my account right afterward, but still was charged when the trial period was up. I contacted them on a Sunday, expecting it to take a few days and be a nightmare. Even though it was the weekend they had it taken care of and refunded to me within a few hours! I would definitely use them again because of how trustworthy and understanding the staff was. Good job PDF Filler Team!

I like the way I can go back and make…
I like the way I can go back and make corrections and print out over and over until I get it right and not being charged for the times I have to print the document.

Why do we use log graphs?
There are two main reasons to use logarithmic scales in charts and graphs. The first is to respond to skewness towards large values; i.e., cases in which one or a few points are much larger than the bulk of the data. The second is to show percent change or multiplicative factors.
What is the significance of a straight line on a log plot?
A plot of the logarithm of the free fall distance as a function of the logarithm of time yields a straight line of slope 2. The slope of a log-log plot gives the power of the relationship, and a straight line is an indication that a definite power relationship exists.
What does a log plot show?
In science and engineering, a log log graph or log log plot is a two-dimensional graph of numerical data that uses logarithmic scales on both the horizontal and vertical axes. ... Any base can be used for the logarithm, though most common are 10, e, and 2.
What is log of a number?
In mathematics, the logarithm is the inverse function to exponentiation. That means the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised, to produce that number x.
What is the difference between a log and a semi log graph?
In a semilogarithmic graph, one axis has a logarithmic scale and the other axis has a linear scale. In log-log graphs, both axes have a logarithmic scale. The idea here is we use semilog or log-log graph axes, so we can more easily see details for small values of y as well as large values of y.
Why do we use semi log graphs?
Semi-log graph paper is simply graph paper which has one linear axis and one log axis. It is used in the case where the data range on one axis is extremely large and/or does not follow a linear progression. ... This will make it much easier to extrapolate data because the range is much more spread out.
How do you find the semi log graph?
The slope of the line can be determined by subtracting the coordinates of two points on the line such that the equation is:
y0 — y1 x0 — x1 ...
log y0 — log y1 x0 — x1 ...
log 1×105 — log 1×107 1 – 0. ...
5 – 7. The slope is equal to about -2. ...
y=-2x+7.
Why is bacterial growth graph on a logarithmic scale?
Why is data for microbial growth generally plotted on a logarithmic scale rather than an arithmetic scale? Helicobacter pylori protects itself from stomach acid by using the enzyme crease to coat itself with ammonia, thereby increasing the pH immediately surrounding it. It prefers a pH of above 5.5!
What does the log function do?
In mathematics, the logarithm is the inverse function to exponentiation. That means the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised, to produce that number x.
How do you use the log function?
Type the number you're working with into your graphing or scientific calculator. For example, type “1000.”
Press the “Log” button on your calculator. The number you immediately see is the exponent for the original number you entered. ...
