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.

For pdfFiller’s FAQs

Below is a list of the most common customer questions. If you can’t find an answer to your question, please don’t hesitate to reach out to us.
How To: Given an equation of the form y = A e k t \\display style y=A{e}^{kt} y=AEK, solve for t. Divide both sides of the equation by A. Apply the natural logarithm of both sides of the equation. Divide both sides of the equation by k.
Logarithm product rule. Logb(x × y) = logo(x) + logo(y) Logarithm quotient rule. Logb(x / y) = logo(x) — logo(y) Logarithm power rule. Logb(x y) = y A logo(x) Logarithm base switch rule. Logb(c) = 1 / logic(b) Logarithm base change rule. Logb(x) = logic(x) / logic(b) Logarithm — log(x) See also.
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. ... Check your work.
A logarithm is the power to which a number must be raised in order to get some other number (see Section 3 of this Math Review for more about exponents). For example, the base ten logarithms of 100 is 2, because ten raised to the power of two is 100: log 100 = 2.
Intro to Adding and Subtracting Logs (Same Base) Logs of the same base can be added together by multiplying their arguments: log(XY) = log(x) + log(y). They can be subtracted by dividing the arguments: log(x/y) = log(x) — log(y).
But you rarely see a calculator which performs a log2 function, which is logarithm with base 2, directly. As an example, calculate log2 of the number 12 i.e. log2(12). To calculate the base 2 logarithms of a number (y), divide the common log of y by the common log of 2.
Example: If you to calculate log(x) base 2, then calculate log(x) base 10 then divide it by log2. Or, to calculate LN(x) base 2, do it with base 10 then divide it by ln2.
Logarithm product rule. Logb(x × y) = logo(x) + logo(y) Logarithm quotient rule. Logb(x / y) = logo(x) — logo(y) Logarithm power rule. Logb(x y) = y A logo(x) Logarithm base switch rule. Logb(c) = 1 / logic(b) Logarithm base change rule. Logb(x) = logic(x) / logic(b) Logarithm — log(x) See also.
Log base 2, also known as the binary logarithm, is the logarithm to the base 2. The binary logarithm of x is the power to which the number 2 must be raised to obtain the value x. For example, the binary logarithm of 1 is 0, the binary logarithm of 2 is 1 and the binary logarithm of 4 is 2.
STEP 1: Replace the function notation f (x) by y. STEP 2: Switch the roles of x and y. × y. y ×. STEP 3: Isolate the log expression on one side (left or right) of the equation. STEP 5: Solve the exponential equation for y to get the inverse. ... Kate is not defined.
