Hence, designers need an effective analog square-root calculator. Because manufacturers do much of the IC fabrication in MOS technology, a MOSFET-based, analog square-root calculator seems appropriate ...

The C language can be used for mathematical operations, ranging from additions and subtractions to square roots and cube roots, along with other polynomial powers that can be created through C ...

Then there was root-mean-square (RMS) voltage. For those nice sine waves, you took the peak voltage and divided by the square root of two, 1.414 or so. You know that kid in the front of the class?

Calculate your T-Value by taking the difference between the mean and population mean and dividing it over the standard deviation divided by the degrees of freedom square root.
