The autosum button will insert the function "=sum(...)" and suggest (highlight) a range it finds most likely - usually adjacent cells above, or to the left, of the cell where you insert the formula.
auto correlation function of a stationary process is an even function
An infinite sum of continuous functions does not have to be continuous. For example, you should be able to construct a Fourier series that converges to a discontinuous function.
It is to convert a function into a sum of sine (or cosine) functions so as to simplify its analysis.
That's called a built-in function; or often simply a "function".
Yes you can.
Clicking on the Autosum button allows you to choose to put the SUM function into a cell, but also gives you a choice of other functions, such as MAX, MIN and AVERAGE.
Yes, you can do that. If you have a series of columns, you can highlight all of the column to select the range. When you click on the auto-sum button, Excel will insert =SUM(XX:XX) at the bottom of each column in the range.
Yes, that is its main function. It can also add individual cells or values or the results of other functions. Here are various examples: =SUM(A2:A20) =SUM(A2,A6,122,A30,B16,20,25) =SUM(MAX(A2:A20),MAX(B2:B20))
why is necessary to auto-save
The autosum button will insert the function "=sum(...)" and suggest (highlight) a range it finds most likely - usually adjacent cells above, or to the left, of the cell where you insert the formula.
ranges evaluated
Assuming you're using Microsoft Excel, select the entire column by clicking and dragging with the mouse, then press the AutoSum button (looks like Σ).
auto correlation function of a stationary process is an even function
If you use Excel in school, then, yes, you can use the SUM function.
The autosum symbol is Sigma, a letter in the greek alphabet.
The average of a set of numbers is equal to the sum of those numbers divided by the number of numbers. So, one might say that the average function is equal to the sum function divided by the count function.
