The sum of n terms of AP is the sum (addition) of first n terms of the arithmetic sequence. It is equal to n divided by 2 times the sum of twice the first term – ‘a’ and the product of the difference between second and first term-‘d’ also known as common difference, and (n-1), where n is numbers of terms to be added.helps math make sense. — and it’s free.

It is called a "common logarithm". Engineers love to use it. On a calculator it is the "log" button. It is how many times we need to use 10 in a multiplication, to get our desired number. Example: log (1000) = log10(1000) = 3. Ceiling Function Formula. The formula to find the ceiling value for any given specified value is: f (x) = minimum { a ∈ Z ; a ≥ x } It is represented by: f (x) = ⌈x⌉ = Least Nearest successive Integer of specified value. Example: Find the ceiling value of 3.7. Answer:The natural logarithm is a logarithm in which the base is the mathematical constant, e. It is written as ln (x) or log e (x).
