So far so good. The only thing I was confused on was that I was able to edit a document before actually registering. Then, finding out later, I could not even print the document without registering. I am not complaining, I was just confused. I am a senior !!

It's easy and I use it for billing for my private practice. There was a recent change in the function of the program that you have that has caused me extra time. I used to be able to look up my form by name using the little magnifying glass and then when I found it, click on the form, and then click on the copy icon. The copy icon isn't present anymore when I look up the form by name, so I instead have to scroll back through all of my forms and it takes a lot longer. If I could still look up by name and then copy the form once I found it that way it would be great. I used to be able to do that until the recent formatting changes.

It's not as intuitive as I hoped to use the mobile apps, and it seems there are many steps to doing the main process which led me to purchase PSF filler--uploading and emailing HIPAA related documents that I've photographed. I'm sure there'll be a learning curve, however, so I am still hopeful.
With two helpful and timely chat guidance, I was able to resolve my problems with scanning and uploading photographed documents quickly. I still wish the mobile app allowed me to rename the document so that I wouldn't have to fiddle with it later in the browser app, but am happy with many other features at this point.

This was a great tool to use as I have suffered a horrible arm injury which made it very difficult to hand write. Your program was a life savior as I had numerous pages of medical documents to file.

Absolute timesaver
Absolute timesaver and easy to use once you are in the form.
It's an absolute timesaver when filling in repetitive forms or having to sign and email something for signature.
Ease of moving around website is a little tricky sometimes

So far so good
So far so good, I would have given it a 5, if downloading my edited documents weren't hidden behind a paywall, but hey, I get it, it is in our nature to capitalize on things where it is impossible to find a solution, few have the solution, so why give it away for free? But yeah, good software none the less.

How do you find the period and amplitude of a graph?

How do you find the period of a graph?
The period of the sine curve is the length of one cycle of the curve. The natural period of the sine curve is 2. So, a coefficient of b=1 is equivalent to a period of 2. To get the period of the sine curve for any coefficient b, just divide 2 by the coefficient b to get the new period of the curve.
How do you find amplitude and period?
Amplitude is the distance between the center line of the function and the top or bottom of the function, and the period is the distance between two peaks of the graph, or the distance it takes for the entire graph to repeat. Using this equation: Amplitude =Period =2BHorizontal shift to the left =Vertical shift =D.
How do you find the midline amplitude and period?

How do you find the period of a function without graphing?
If your trig function is either a tangent or cotangent, then you'll need to divide pi by the absolute value of your B. Our function, f(x) = 3 sin(4x + 2), is a sine function, so the period would be 2 pi divided by 4, our B value.
