of them was the "Newton equation solving" model. I always thought this name was so domineering (after all, it had something to do with Newton ).Newton's equation solving is very useful. For example, if you want to solve an equation (one dollar), you can simply enter the equation into a calculator. It is very useful (for me, a careless and lazy person, it cannot be better ). I have never known why this mode

object, the object will also apply a reverse reaction to the Earth. Because the earth is much larger than the object mass, the gravity of the object on the Earth has no effect on the Earth. However, if you have a larger object, such as the sun, the gravity of the earth is much less than that of the sun. Fortunately, our Earth always rotates around the sun in orbit, the moon rotates around the Earth in the same way. Figure 13-2 In his book "mathematical principles",

Newton Iteration For more information, see Wikipedia http://zh.wikipedia.org/wiki/niudon. Example: Square Root Returns the square root of a number. If the square root of X is set to x, x ^ 2-A = 0. If f (x) = x ^ 2-, Take the initial value of x0 as close as possible to the square root of a (because the selection of initial values affects the number of iterations) According to F (x0) = (x0-x). f' (x0) ---> X = x0-F (x0)/F' (x0) ① ---> X0 = x ② Rep

Today is the birth of the great British mathematician and physicist Isaac Newton. Google made a commemorative logo for it. The logo conforms to the subject and is vivid and playful. See the figure below. Figure 1 Figure 2 In Figure 1, apple fell to the ground according to the track in Figure 2. The specific effect is that I have to admire the imagination of the logo designer. The result is displayed. Let's see how it is implemented. First look at t

There are many ways to find the square root, here is the Newton method to find the square root.The method is this: if you have a guess Y for the value of the square root of x, then you can get a better guess by doing a simple operation: only the average value of Y and X/y is required (he is closer to the actual square root)Code implementation:float sqrt (float x) { float guess = x; while 0.0001 ) { 2; } return guess;}Note: Th

Numerical Computation has just learned the Newton Iteration Method to Calculate the zero point of the equation. Today we can see that poj has questions about this. The key to this question is to know the formula. G (x) = x-(x-A/X)/2 can be iterated based on this formula. The termination condition is that the number of iterations is less than 1e-6. # Include

Newton's Iterative method was used to find the root of the equation near 1.5:2x^3-4x^2+3x-6=0.Solution: Newton's Iterative method is also called Newton tangent method.

Using Newton's Iterative method to find the root of the following equation near 1.5:2x^3-4x^2+3x-6=0 As for the Newton iterative method, in the course of computational methods, the basic formula is: xn+1=xn-f (Xn)/F *(Xn) xn+1 is the n+1 iteration result,Xn is the nth iteration result,f * ( Xn) is the Guide function value of f (Xn) . Basic steps: The first step is to rewrite the equation as polynomial f (x) =2x^3-4x^2+3x-6, given initial value X0; T

First, to discuss a simple example, if you want to find the point of the function f (x) =0, you can do the following.If our initial value is X0, then the tangent of f (x) at that point, looking for a tangent to the x-axis intersection, the point as a known point, looking for a tangent, repeat the above operation, you can quickly approximate f (x) =0 point.The idea is used to solve the maximum likelihood function, the general maximum value satisfies = 0, then the operation can be done.
