I love it for my business. It makes it so much easier to have a completely paperless office. We can just scan things into the computer and edit them or use as a document on PDFfiller.

kind of difficult to understand..sometimes it would not fill out the form and sometimes it would, then go back to the first signature and had to keep confirming.

It's not as easy to follow as you think it is. For example, Save As is a command that most of us think as a file name, not application such as PDF or Docx. I now have to go back and find the document, add the signature and then, change the name of the file, somehow from the template to a specific client's file.

Helpful Tool
I had been trying to send off some release forms and was crunched for time so I signed up for PDFFiller's free trial. In the end, I wasn't able to use their software without a purchase, but it made me almost wish I had paid the money.
I like that I can sign any document electronically. It definitely saves time and printing costs. It cuts out about 2 extra steps: printing and scanning. This is helpful for documents that need signatures such as release forms, etc.
I didn't like how much I had to pay in order to use my e-signed pdf. I don't use the software often enough to make it worth the price.
However, if I worked regularly with documents that needed to be signed this software would be the very best solution.

For the times i needed pdfFiller, it served me well, but it is not that easy yet for me to use as I am not aware of all te the tools it provides me.

It would help to have some sort of tutorial outlining the all the functions. Having been offered a webinar during the 30 day free trial would've been helpful.

works great special on distance learning for my grade schooler.we are stranded in a 3rd world country and schools are limited because of quarantine.

I have used it several times and it works great!
I like the eSign feature that allows me to create important documents and sned them via email to get signed.

All I needed was to fill in 5 W2 2024 forms for church staff, and pdfiller was easy to use. Since I won't be needing it for anything else, I don't want the charge on my card. I will remember pdfiller should a future need arise.

What is the formula for resolution?
Equation (1) indicates that the resolution is the difference between peak retention times divided by the average peak width. In a peak with Gaussian distribution, the peak width is W = 4 (where is the standard deviation) and the peak FHM is W0. 5h = 2.354.
How do you calculate resolution of a microscope?
NA= n x sin Where n is the refractive index of the imaging medium and is half of the angular aperture of the objective. D= /2 NA. Where is the wavelength of light used to image a specimen. D= 2 /NA2 R= 1.22 /Naomi+Second.
How do you determine the resolution of a microscope?
The resolution of an optical microscope is defined as the shortest distance between two points on a specimen that can still be distinguished by the observer or camera system as separate entities.
What is the resolution of a compound microscope?
In a compound microscope, the wavelength of the light waves that illuminate the specimen limits the resolution. The wavelength of visible light ranges from about 400 to 700 nanometers. The best compound microscopes cannot resolve parts of a specimen that are closer together than about 200 nanometers.
How would one improve the resolution of the microscope?
The resolution of a specimen viewed through a microscope can be increased by changing the objective lens. The objective lenses are the lenses that protrude downward over the specimen. Grasp the nose piece. The nose piece is the platform on the microscope to which the three or four objective lenses are attached.
What is the limit of resolution?
The limit of resolution (or resolving power) is a measure of the ability of the objective lens to separate in the image adjacent details that are present in the object. It is the distance between two points in the object that are just resolved in the image.
What factors affect resolution of a microscope?
The primary factor in determining resolution is the objective numerical aperture, but resolution is also dependent upon the type of specimen, coherence of illumination, degree of aberration correction, and other factors such as contrast-enhancing methodology either in the optical system of the microscope or in the
