Finding the root x^3-5x^2+16x-80=0 of a three-order equation by using the chord-truncation method#include #include float f (float x)//define sub-function f (x) = X^3-5x^2+16x-80, when f (x) →0, then x is the real number root of th

Obtain a solid root of the high equation 2x ^ 4-4x ^ 3 + 6x ^ 2-8x-8 = 0 (accuracy requirement: 10 ^-3) Algorithm analysis is as follows: There are many real-root algorithms for High-Level equations. Here we introduce a kind of bipartite method. If the higher-order equation

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. Setf =2x^3-4x^2+3x-6,F1 is the derivative of the equation, thef1 = 6x^2-8x+3, and f1= (f (x0) -

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

Init is one of the most indispensable programs in Linux system operation. Init process, which is a user-level process initiated by the kernel. The kernel will find it in several places in the past that used Init, and its correct location (for Linux systems) is/sbin/init. If the kernel cannot find Init, it will try to run/bin/sh, and if it fails, the boot of the system will fail.Linux 7 RunLevel (0: shutdown, shutdown mode,1: single-user mode,2: Multi-

Android's silent installation seems like an interesting and tempting thing to do, but in common practice it seems difficult to install silently if the phone does not have root privileges, because Android does not provide the intent call that is displayed, typically by installing APK in the following ways: Intent Intent = new Intent (intent.action_view); Intent.setdataandtype (uri.fromfile (file), "

This article describes how to use the root permission to silently install the APK, how to automatically select normal installation or silent installation, and how to expand PackageUtils to delete the APK silently. 1. Silent Installation and call with root permission Directly call the PackageUtils. installSlient functio

In the apk, sometimes the root permission is required, such as updating system files such as system files through the apk, to avoid upgrading the firmware or directly accessing certain devices in the apk. The following method is used to obtain the root permission in

This article describes how a virus can tamper with a superuser so that the root permission of a virus request is allowed to be permanently used by the virus. Continue with the previous two articles. If you have any questions, read the first two articles first. In other words, your fake.apk must copy the application to the system. This requires the root permission. If the user allows you to copy a
