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) -0)/(X0-X1),

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 (

is no need to modify the original method of loading images, and do not need to modify xib loading pictures, but make sure there is a set of @3x pictures This method is only used for iOS8 system, because it has been verified that the system above iOS8 has been automatically adapted to the image.

The traditional font size adaptation may fit according to the width of the screen with a ratio of iphone5 or iphone6 width. But if there is a need to display a font on the phone that displays the @2x picture, another fixed-size font appears on the phone that displays the @3x picture.So the point here is to distinguish between the screen display of the mobile phone is the @2x type or the @3x type.CGFloat sca

IOS only uses the 3x image solution (source code included), ios3x With the introduction of 6 plus by Apple, image resources have become a major problem. 2x-640x960 2x-750x1334 3x-1242x2208. The installation packages of various types of images will inevitably increase a lot, so many types of images will inevitably be missed, therefore, you have written a Category library for UIImage. You only need to add a

Based on the data, Excel uses the chart to represent the curve of the mathematical function y=3x+4, we have to use XY scatter chart to achieve the curve effect! The method is as follows: first, establish the data region of the following figure. A1 Enter a constant of 4, then the B column enters the range of independent variables such as [ -5,5], as the scope of the change of X. Then, in column C, we have to reflect the value of the Y va
