WebFeb 16, 2006 · To calculate the root-mean, one may simply apply Newton's Method for calculating the square root to the mean value. As long as the averaging time is long compared to the sample period (t &62;&62; 1/f S), one iteration of the square root calculation should suffice for reasonable accuracy. This seems simple enough, but we … WebSquare root approximation with Newton's method. I designed a program that calculates the square root of a number using Newton's method of approximation that consists of taking a guess ( g) and improving it ( improved_guess = (x/g + g)/2) until you can't improve it anymore: #include #include using namespace std; template ...
