Solution The first step in solving this initial-value problem is to find a general family of solutions. To do this, we find an antiderivative of both sides of the differential equation ∫y′ dx = ∫(3ex + x2 − 4)dx, namely, y + C1 = 3ex + 1 3x3 − 4x + C2.

WebJan 9, 2024 · Use the Laplace transform to solve the initial value problem y ″ − 6y ′ + 5y = 3e2t, y(0) = 2, y ′ (0) = 3. Solution Taking Laplace transforms of both sides of the differential equation in Equation 7.3.6 yields L(y ″ − 6y ′ + 5y) = L(3e2t) = 3 s − 2, which we rewrite as L(y ″) − 6L(y ′) + 5L(y) = 3 s − 2. Now denote L(y) = Y(s).

Webno independent variable was speciﬁed, MATLAB used its default, t. For an example in which the independent variable is speciﬁed, see Section 4.1.1. To solve an initial value problem, we simply deﬁne a set of initial values and add them at the end of our dsolve() command. Suppose we have x(0) = 1, y(0) = 2, and z(0) = 3. We have, then, WebNDSolve issues a warning message because the matrix to solve for the initial conditions is singular, but has a solution: In [117]:= Out [117]= You can identify which solution it found by fitting it to the interpolating points.
