Professor Xiong Qinglai, chairman of the Department of mathematics of Tsinghua University, attached great importance to his paper Su Jiaju's reason why the solution of algebraic quintic equation cannot be established. At the recommendation of Professor Xiong, he went to work in Tsinghua University in 1931. The life of Hua Luogeng Bo Le knows horses a paper reasons for the quintic equation of Su Jiaju's algebra a Bo Le (Xiong Qinglai) made a turning point in his life (laying the foundation for the success of future mathematicians) Famous. Hua Luogeng is a famous mathematician who is self-taught and famous at home and abroad.

This kind of math problem is not an example. At first glance, some primary school math problems are very simple, but in fact there are hidden traps. Playing around seems like a brain teaser. Parents never did such flexible math problems when they were children, so it is not so simple to tutor primary school students. Parents must also use their brains.

How to calculate the sum of squares on the left or right side of the equation? They are the sum of the squares of the consecutive natural numbers after the first several items are incompletely removed. The sum of the squares of the previous several items is subtracted from the sum of the squares of the n items, and the rest is the sum of the squares of the required consecutive natural numbers Since their left and right sides are equal, they can be calculated with several squares on the right side, and they don't need a calculator or a draft paper at all. It's OK to write steps while doing mental calculations. Of course, this is a case where the number of calculation items is relatively small.

as long as the product of the two quantities is certain, the inverse proportion equation can be listed by the inverse proportion relationship. It is easy to prove that the wave function in the variable separation form used above is the common eigenstate of the Hamiltonian of the moving part of the center of mass and the Hamiltonian of the relative moving part. Zhang Chaoyang proved that in the case of non degeneracy, two commutative operators have a common eigenstate. On the contrary, if the common eigenstates of the two operators can form a complete basis of the Hilbert space, then they are commutative. From this, it can be concluded that the Hamiltonian operator of the center of mass motion and the Hamiltonian operator of the relative motion are commutative, which indicates that if we want to solve the eigenequation of the Hamiltonian operator by the method of separating variables, we need to decompose the Hamiltonian operator into reciprocal operators, and solve the eigenequation of the original Hamiltonian by solving the simple eigenequations of these reciprocal operators, which is exactly the method we use to solve the Schrodinger equation of the steady state of the hydrogen atom.

GMAT's mathematical questions are multiple-choice questions, and no calculator is provided. It mainly examines the examinee's ability to mathematical reasoning, solve quantitative problems and interpret graphical data. The difficulty of the questions comes from the required logic and analysis ability, not the basic mathematical calculation ability. In terms of the key points of the examination, the college entrance examination mathematics focuses on formula deduction, mathematical definition and principle; DSE mathematics focuses on application and calculation. Therefore, the DSE math exam can use a designated model of calculator, and the calculator can also set up programs to help calculate triangles, trajectories and equations, functions, etc.
