This program was easy to work with; however, I misunderstood that the forms I was trying to use were copyrighted and had to be completed in another manner. Customer service was very prompt in responding to questions; and, for the right forms, this would be an awesome service.

Amazed at the accessibility and ease of use! Thank you for the free trial. Having the free trial gives me a chance to determine if this is something I can utilize on a regular basis before expending the cost. Thank you.

Best Friendly user software
It was great, very useful when it came to modify and add wordings to documents or even signatures.
I like the availability to modify and edit your documents, it's very easy to use and it has so many features to get your documents corrected, sent, faxed, emailed and more.
I didn't like when adding texts to your documents, sometimes it will freeze and close the program. Then again it was the free trial.

This was my first experience with completing a 1099-NEC. It took me a while to figure out what to do. I really enjoyed it. I hope I haven't duplicated

Really good platform.
Just try to fix the bug while opening documents at the dashboard.
The bug is the following:
Click on open item button
It will send to authentication page.

I paid for the first 30 days to make sure that I would be happy with this tool. I am very satisfied with 99% of the editing and use tools. No ability to grab and move sections of existing form just new items.

What is the formula for resolving power?
The minimum angular separation of two points which can just be resolved by an optical instrument is given by min = 1.22 /D, where D is the diameter of the aperture of the instrument.
How do you calculate resolving power?
= wavelength. U = angle of the cone of light coming from object. U' = angle of cone of light forming image. N = refraction index of object. M = magnification. NA = numerical aperture. D = distance between two points in the image. D = 0.61 / (m tank') (1)* **
How do you calculate the resolving power of the eye?
The diffraction limit of the eye can be calculated using Rayleigh's criterion: angular resolution = (1.22)(lambda)/D, where lambda is the wavelength of light (on the average, about 550 nm) and D is the diameter of the eye's pupil, which is about 5 mm indoors.
What is the resolving power of microscope?
Resolving power is defined as the ability of a microscope or telescope to distinguish two close together images as being separate. An example of resolving power is how well a telescope can show two stars as being separate stars.
How do you calculate resolving power of grating?

What is the formula of resolving power of a microscope?
Resolving Power. The resolving power of an objective lens is measured by its ability to differentiate two lines or points in an object. The greater the resolving power, the smaller the minimum distance between two lines or points that can still be distinguished.
What is the resolving power of a microscope?
Resolving power is defined as the ability of a microscope or telescope to distinguish two close together images as being separate. An example of resolving power is how well a telescope can show two stars as being separate stars.
What is the formula of resolving power of telescope?
For telescope: Resolving power = D/1.22, here D is diameter of aperture, and lambda is the wavelength of light used. For microscope: Resolving power = 2usin@ / 1.22, here u = refractive index, @ = angle subtended by object on objective, lambda is wavelength.
