WebApr 12, 2024 · The search for general methods of integrating differential equations originated with Isaac Newton (1642--1727). Even though Newton noted that the constant coefficient could be chosen in an arbitrary manner and concluded that the equation possessed an infinite number of particular solutions, it wasn't until the middle of the 18th … WebDifferential Equations of Second Order. Like differential equations of first, order, differential equations of second order are solved with the function ode2. To specify an initial condition, one uses the function ic2, which specifies a point of the solution and the tangent to the solution at that point. Example: eq: 'diff(y, x, 2) + y = 0 ...
