WebCount unique values in Excel. You can use the combination of the SUM and COUNTIF functions to count unique values in Excel. The syntax for this combined formula is = SUM (IF (1/COUNTIF (data, data)=1,1,0)). Here the COUNTIF formula counts the number of times each value in the range appears. The resulting array looks like {1;2;1;1;1;1}. Web1 Feb 2024 · This study investigates linear fractional difference equations with respect to interval–valued functions. Caputo and Riemann–Liouville differences are defined. …

Web8 Nov 2024 · Convolutions. Suppose X and Y are two independent discrete random variables with distribution functions \(m_1(x)\) and \(m_2(x)\). Let Z = X + Y.We would like to determine the distribution function m3(x) of Z. To do this, it is enough to determine the probability that Z takes on the value z, where z is an arbitrary integer.Suppose that X = k, … Web15 Jun 2024 · Differentiation of Sums and Differences Here are the differentiation rules for the sum and difference of two functions: d d x [ f ( x) + g ( x)] = d d x [ f ( x)] + d d x d d x [ g ( x) and d d x [ f ( x) − g ( x)] = d d x [ f ( x)] − d d x [ g ( x)] In simpler notation ( f ± g) ′ = f ′ ± g ′ naval action rattlesnake heavy
