What is the equation method?
equation method. method used to find the break-even point or target income volume in Cost-Volume-Profit (CVP) Analysisor break-even analysis. The equation is: Sales = Variable Costs + Fixed Costs + Net Income. Let p = unit selling price, x = volume, v = unit variable cost, and FC = total fixed costs; the equation …

What is linear and nonlinear partial differential equations?
Linear Partial Differential Equation If the dependent variable and all its partial derivatives occur linearly in any PDE then such an equation is called linear PDE otherwise a nonlinear PDE. In the above example (1) and (2) are said to be linear equations whereas example (3) and (4) are said to be non-linear equations.
Is Riccati equation linear?
the equation becomes a first order linear ordinary differential equation.
How do you solve Riccati differential equations in Matlab?
The following method will solve the matrix Riccati differential equation. Save the following as a MATLAB file somewhere on the MATLAB Path. function dXdt = mRiccati(t, X, A, B, Q) X = reshape(X, size(A)); %Convert from “n^2”-by-1 to “n”-by-“n” dXdt = A. ‘*X + X*A – X*B*B.
How is the break-even point calculated?
In accounting, the breakeven point is calculated by dividing the fixed costs of production by the price per unit minus the variable costs of production. The breakeven point is the level of production at which the costs of production equal the revenues for a product.
What is nonlinear differential equation?
A non-linear differential equation is a differential equation that is not a linear equation in the unknown function and its derivatives (the linearity or non-linearity in the arguments of the function are not considered here). Linear differential equations frequently appear as approximations to nonlinear equations.
What is non-linear partial differential equation with example?
If the function F depends linearly on its highest derivatives, then (1) is called a quasi-linear equation. For example, (3) is quasi-linear. Otherwise the equation is called an essentially non-linear equation. For example, the Monge–Ampère equation (2) is essentially non-linear.
What is nonlinear equation?
A Nonlinear equation can be defined as the equation having the maximum degree 2 or more than 2. A nonlinear equation forms a curve on the graph. The general form of linear equation is, y = mx +c. Where x and y are the variables, m is the slope of the line and c is a constant value.
