# Solving definite integrals

In this blog post, we will explore one method of Solving definite integrals. Let's try the best math solver.

## Solve definite integrals

In algebra, one of the most important concepts is Solving definite integrals. Next: study the nature (or method). Be able to discriminate concepts, which means that you really understand equations. For an equation, if it contains unknowns, it must be solved. Therefore, after you can accurately judge the equation, you are faced with how to solve the equation.

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.

Liu made seven mistakes in her algebra homework of 16 questions. Her father was very angry and asked her daughter to do it again, but Ms. Liu was very unconvinced and reasonable. Teacher Liu Taotao shared on behalf of the third grade: she proposed to design around algebra, geometry, synthesis and practice. Geometry knowledge points account for a large proportion in primary school math courses, and are common in our daily life.

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.

However, in the real situation, we can't meet so well-designed data, and the resulting equation may not be reducible on mathbq, so we can't even do the first step This forces us to seek more general methods to obtain such good things as the root finding formula of quadratic equations, so that we can solve arbitrary polynomial equations. This is what people have pursued in history The core of the infinite self similarity method is to establish a shape such as R_ infty=R_ {infty + 1}. In this method, because series and parallel exist at the same time, it is often necessary to solve the quadratic equation, which usually has two roots. For pure resistance networks, these two roots can clearly judge the positive and negative, so that one of them can be easily excluded. However, when there are inductance, capacitance and other components in the circuit, this judgment method needs to be improved.
