The first time I was in school for electrical engineering (long story), I had a professor who had never worked in the industry. I was in her class and the topic of the day was measuring AC waveforms.

Mastering quick square root calculations boosts maths exam performance. Speed and accuracy provide a significant advantage in algebra and geometry. Memorising key square roots and using mental math ...

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, ...
