or square root of a value by using the formula creator. Input your first value in the desired cell; for example, input "3" into "D1." Double-click an empty cell adjacent to the first. For this ...

Square-root-calculating circuits find wide use in instrumentation and measurement systems for such tasks as calculating the rms (root-mean-square) value of an arbitrary waveform, for example. Hence, ...

with the average value subtracted off beforehand. You even calculate the hypotenuse of a triangle by the same procedure, just without dividing by n. (OK, that’s a stretch, but square roots of ...
