In addition to counting cells that meet multiple conditions set by the user, the SUMPRODUCT function can also sum the contents of those cells.
Even though Excel has the better known SUMIF and SUMIFS functions to add up values that meet one or more conditions, SUMPRODUCT still has its uses.
One such use is summing the data in cells that fall between two values.
For more information, read this short tutorial on how to Sum Cells between Two Values with SUMPRODUCT.

Count Cells with SUMPRODUCT
© Ted French
SUMPRODUCT is one of Excel's more unique functions.
For one, it is undocumented, which means it does not get listed with other functions, nor does it provide users with the dialog box option for filling in the function's arguments.
Second, in addition to its normal job of adding together the results of multiple multiplication operations, it can also be used to count up the number of cells in a range that meet specific criteria.
To find out more, read this short tutorial on how to Count Cells between Two Values with SUMPRODUCT.

Excel has a number of functions that can help you carry out basic trigonometry operations such as finding the tangent or cosine of an angle.
The only problem is that these functions require that angles be measured in radians.
Since most of us measures angles in degrees, Excel has a function that converts these degree measurements to radians.
In doing so, Excel makes using its trig functions as is easy as Pi.
To find out all the details on using this handy function, read the tutorial on the Excel RADIANS Function.

Another of Excel's trigonometric functions includes the COS function which is used to find the cosine of an angle.
Trigonometry has application in a number of fields including astronomy, physics, engineering, and surveying.
In particular, the uses for the cosine of an angle include modeling such things as sound and light waves.
