It is a PDF editor very easy to use and very useful! It has helped me a lot to edit PDFs and very easily, when before it was impossible. You can upload a document from your computer, but also from Dropbox, Box and OneDrive. With any option, you can edit by adding images, signatures, text boxes and brands. As a disadvantage, the file load is a bit slower than other editors. however, it provides great editions.

The natural logarithm has the number e (that is b 2.718) as its base. Its use is widespread in mathematics and physics, because of its simpler integral and derivative. The binary logarithm uses base 2 (that is b = 2) and is commonly used in computer science. Logarithms are examples of concave functions.
The binary logarithm uses base 2 (that is b = 2) and is commonly used in computer science. Logarithms are examples of concave functions. Provided that b, x and y are all positive and b 1. The slide rule, also based on logarithms, allows quick calculations without tables, but at lower precision.
Logarithms are a way of showing how big a number is in terms of how many times you have to multiply a certain number (called the base) to get it. The most common numbers to use are 2, 10, and 2.71828). Logarithms are useful because they are the way our brain naturally understands most things.
Using Logarithmic Functions Some examples of this include sound (decibel measures), earthquakes (Richter scale), the brightness of stars, and chemistry (pH balance, a measure of acidity and alkalinity). Let's look at the Richter scale, a logarithmic function that is used to measure the magnitude of earthquakes.
To solve a logarithmic equation, rewrite the equation in exponential form and solve for the variable. Example 1: Solve for x in the equation Ln(x)=8. Check: You can check your answer in two ways. You could graph the function Ln(x)-8 and see where it crosses the x-axis.
The equation log x = 100 is another way of writing 10x = 100. This relationship makes it possible to remove logarithms from an equation by raising both sides to the same exponent as the base of the logarithm. If the equation contains more than one logarithm, they must have the same base for this to work.
