Ideas: 1, first understand what is called a two-time equation, when a is not equal to 0, this equation is a two-time equation2, according to the formula Derta=b*b-4*a*c to determine the root of the situation①derta>0, the equation has two unequal real roots②derta=0, the equation has two equal real rootsWhen ③derta3, fir

I have to say, Mathematica is a really good thing, before learning finite element, for the equation deduction in the book, see the past, never thought to deduce it yourself again, because the manual derivation is too complex. With the MM, the original very complex things suddenly become simple. 1. Unit Geometry Description is pure curved beam unit, length L, modulus e, area A, moment of inertia I. The displacement arrays of two nodes 1 and 2 are \[Q^

Teaching objectives: 1. Understand General Dynamics equations. 2. Use the Laplace equation correctly to establish the moving differential equations of the point system. Highlights and difficulties of this chapter: Select generalized coordinates, and express the particle kinetic energy as a function of generalized coordinates and generalized velocity. Calculate the generalized force or represent the potential function of the conservative system as a

When you do this for the first time, use the probability as a backpack (enlarge 100000 times to an integer ): in this range, what's the most frustrating is to think of the total probability as the sum of the probability of robbing n Banks...

From Link: enumz1) solving a modal linear equation ax = b (mod n)Equation ax = b (mod n), ax = b + NY->ax-ny = b-AX + N (-y) =b where a,n,b is known. A set of special solutions to this equation can be obtained by expanding Euclidean.Here are some theorems for solving the equation:1. When and only when d|b, the

In probability theory, especially in stochastic process theory, the Chapman-kolmogorov equation is an important conclusion. It links the joint distribution functions of several different dimensions of a stochastic process. If the stochastic process is specific to a Markov chain, then the Chapman-kolmogorov equation is the formula for the transfer probability. I hope you understand the following two prelimin

This is my study notes, the course for NetEase Open Class Stanford University Open Class: Fourier transform and its application.Thermal equation Follow-upThe Fourier coefficients of the thermal equation are deduced from the previous lesson:$C _k (t) = c_k (0) e^{-2\pi ^2 k^2t}$So what is $c_k (0) $?The previous lesson mentioned that temperature has the following relationship:$U (x,t) = \displaystyle{\sum_{k

Question: solving the quadratic equation of one element: the solution of ax ² + bx + c = 0, where a = 1, B =-3, C = 2. Analysis: We all know that there are three solutions to the quadratic equation of a single element, that is, considering the arithmetic square root of △= (b²-4ac). When △> 0, the equation has two unequal real root X1 = (-B + SQRT (D)/(2a); x2 = (

§ 4 spatial Linear Equation General equation of a Spatial Straight Line: The Spatial Straight line can be regarded as the intersection of two planes. In fact, if the plane and equation of the two intersections are : : Then, the coordinates of any point on the Spatial Straight Line satisfy both the plane equations, that is, the equations must be satisfied. (3.4-1)

How does PHP find the root of a quadratic equation ?. Today, someone has a mathematical question: 4x + 1x2. how much is x. Converting the equation, 4x2 + 12x, and then 4x2 + 2x + 10, is actually a problem of the unary quadratic equation. For a long time, no one has a mathematical problem today. 4x + 1/x = 2. how much is x. Convert the
