How to Use the Newton method to find the square root of a number

An exercise for Scip 1.1.7. The Newton's method is also called the Newton-Raphson method ), it is an approximate method proposed by Newton in the 17th century to solve equations in real and complex fields. Most equations do not have root formulas,

Written question: Ask for a number of the root, such as the square root 2

Title:The root of a number, such as the square root 2, is required to be reserved to 10 digits after the decimal point. Solution One:It is equivalent to seeking a number N of the root, we use the dichotomy method to calculate, shrinking the range,

Calculation of the square root of an integer (1)

  Abstract: This paper mainly discusses how to calculate the square root of a small integer by using the sum of the number of series. This algorithm can accurately return the square root of an integer to any precision when the memory space permits.

Underlying algorithm efficiency of the square root sqrt () function

Although you may not have thought about this problem at ordinary times, it's not that easy to say that it's just like "getting a gun in front of a while, it's not that simple, we use the binary method to test the number of squares in the middle of

Calculate the square root using Newton Iteration Method

Evaluate the square root of N. Assume that x 0 = 1 is the predicted value. Then, calculate the X1 according to the following formula, then substitute X 1 into the right of the formula, and continue to obtain the X2... After an effective iteration,

Mean value, variance, mean square value, mean variance calculation and their physical meaning in digital signal processing

1 mean value The mean value represents the size of the DC component in the signal, expressed in E (x). For a Gaussian white noise signal, its mean value is 0, so it has only the AC component. 2 square of the mean value The square of the mean,
