2021-4-14  A breather is a localized periodic solution of either continuous media equations or discrete lattice equations. The exactly solvable sine-Gordon equation and the focusing nonlinear Schrödinger equation are examples of one-dimensional partial differential equations that possess breather solutions. Discrete nonlinear Hamiltonian lattices in many cases support breather solutions.

#### quantum mechanics Why can't the Schrödinger

2021-4-7  The problem is not at all unique to Schrödinger's equation, it is a common feature of differential equations. The same thing happens all over the place in classical electro-magnetics. But, also to say there is no "exact" solution is misleading. It is more true to say that the solution cannot be expressed finitely in certain notations.

#### [2103.04153] The Solution of the Long-Wave Equation

2021-3-6  We show that for these types of power-law forms of depth and breadth profiles, the long-wave equation admits solutions in terms of Bessel functions and Cauchy-Euler series. We also derive the seiching periods and resonance conditions for these forms of depth and breadth variations.

okay I filled your brain with a bunch of partial derivatives and XY's with respect to X's and Y's I think now it's time to actually do it with a real differential equation and make things a little bit more concrete so let's say I have the differential Y the differential equation y cosine of X plus 2x e to the y plus sine of X plus already running out of space x squared e to the Y minus 1 times

A solution (or particular solution) of a diﬀerential equa-tion of order n consists of a function deﬁned and n times diﬀerentiable on a domain D having the property that the functional equation obtained by substi-tuting the function and its n derivatives into the diﬀerential equation holds for every point in D

2021-4-14  A quadratic equation with real or complex coefficients has two solutions, called roots.These two solutions may or may not be distinct, and they may or may not be real. Factoring by inspection. It may be possible to express a quadratic equation ax 2 + bx + c = 0 as a product (px + q)(rx + s) = 0.In some cases, it is possible, by simple inspection, to determine values of p, q, r, and s that make

#### Chemical equation balancer (JavaScript)

The only mathematical solution to your equation has all coefficients set to zero, which is a trivial solution for every chemical equation. For example, C → N 2 has no solution because the only solution is 0C → 0N 2. Multiple independent solutions. There exist multiple solutions to your equation that are not simply multiples of each other.

#### SOLVING EXPONENTIAL EQUATIONS

2012-12-28  To solve an exponential equation, take the log of both sides, and solve for the variable. Example 1: Solve for x in the equation . Solution: Step 1: Take the natural log of both sides: Step 2: Simplify the left side of the above equation using Logarithmic Rule 3: Step 3: Simplify the left side of the above equation: Since Ln(e)=1, the equation reads Ln(80) is the exact answer and x=4

#### Equation Solver Solve for x Calculator Online

Example: \$ 2x=1 \$ returns for solution \$ x=1/2 \$ dCode returns exact solutions (integers, fraction, etc.) by default (for linear and nonlinear equation systems), if the equation contains comma numbers then dCode will return a solution with decimal numbers. Example: \$ 2x=1.0 \$ returns for solution \$ x=0.5 \$

#### Integral equation Wikipedia

2021-4-14  Integral equations as a generalization of eigenvalue equations. Certain homogeneous linear integral equations can be viewed as the continuum limit of eigenvalue equations.Using index notation, an eigenvalue equation can be written as,= where M = [M i,j] is a matrix, v is one of its eigenvectors, and λ is the associated eigenvalue.. Taking the continuum limit, i.e., replacing the discrete

#### Solve a Quadratic Equation in Excel Easy Excel Tutorial

2021-3-29  Note: Excel returns the solution x = 5. Excel finds the other solution if you start with an x-value closer to x = -1. For example, enter the value 0 into cell A2 and repeat steps 5 to 9. To find the roots, set y = 0 and solve the quadratic equation 3x 2 12x + 9.5 = 0. In this case, set 'To value' to 0.
