The Best Math problems with answers

In this blog post, we discuss how Math problems with answers can help students learn Algebra. The principal component analysis transform of noise adjustment is basically equivalent to MNF transform, except that the problem of solving generalized eigenvalues is simplified. In the diagonal matrix obtained by napc transformation, the diagonal elements need to meet the condition that they are greater than or equal to 1. After general napc transformation, the eigenvalues of the last few components are close to 1. When the median filtering method is used to evaluate the noise matrix, the eigenvalues of some elements of the diagonal matrix obtained are less than 1.

The separation algorithm based on pressure solves the governing equations in sequence (that is, solves the governing equations separately from each other). Because the governing equations are nonlinear and coupled, it is necessary to iteratively execute the solution cycle to obtain a converging numerical solution. In the separation algorithm, the solution variables (such as pressure term, temperature term, speed term, etc.) are solved one by one by individual control equations. Each control equation is decoupled or separated from other equations when solving, so it is named. The separation algorithm is stored in real time, because the discretized equations only need to be stored one at a time.

It uses a single transformation to convert a dense matrix into a Hessenberg matrix. In this algorithm, Arnoldi algorithm first calculates the eigenvalues of the Heisenberg matrix in less steps, and then uses these eigenvalues as clues to calculate the eigenvalues of the original matrix. Later, it is found that this strategy is very effective for approximating the eigenvalues of large sparse matrices, and can be further extended to solve large sparse linear systems. When solving the linear equations, we will convert the coefficient matrix / augmented matrix into a row ladder matrix through a series of elementary row transformations. Then this series of elementary row transformations can be equivalent to sequentially left multiplying the corresponding elementary matrix The Gauss elimination algorithm for solving general ntimesn linear equations includes two basic steps: forward elimination (rotation and shear) and backward substitution (scaling).

This question mainly examines the comprehensive application of the sine theorem, the tangent formula of the sum of two angles, the cosine theorem, and the area formula of triangles in solving triangles, and examines the transformation idea, which belongs to the basic question. Question 17. This question mainly examines the comprehensive application of the sine theorem, the tangent formula of the sum of two angles, the cosine theorem, and the area formula of triangles in solving triangles, and examines the transformation idea.

The Hong Kong University of science and Technology (Guangzhou) is a key construction project of Guangzhou Nansha Guangdong Hong Kong Macao comprehensive cooperation demonstration zone. The first phase of the project (supporting buildings) has a total construction area of 360000 square meters, including 304000 square meters of above ground construction area and 56000 square meters of underground construction area. There are 39 single buildings in total, including student dormitories, teacher dormitories, stadiums and auxiliary living facilities. (4) For the building projects that have obtained the green transformation evaluation mark of existing buildings, the reward and compensation will be given according to the building area: 15 yuan / square meter for one star; Two star 30 yuan / square meter; Three star 50 yuan / m2; The maximum award and subsidy area of a single project shall not exceed 20000 square meters.
