Initial value problem with two variables
Webb21 okt. 2011 · Initial Value Problems. Most general-purpose programs for the numerical solution of ordinary differential equations expect the equations to be presented as an explicit system of first order equations, \tag {1} y' = F (t,y) that are to hold on a finite interval [t_0, t_f]\ . An initial value problem specifies the solution of interest by an ... WebbIn the previous example, the initial-value problem consisted of two parts. The first part was the differential equation [latex]{y}^{\prime }+2y=3{e}^{x}[/latex], and the second part was the initial value [latex]y\left(0\right)=3[/latex]. These two equations together formed …

Webb20 juli 2024 · If you still want to use DSolve, you have to substitute the y [x] with a ReplaceAll and a Part to get rid of the List. This looks like this: sol = (y [x] /. DSolve [ {y' [x] == x^2*y [x], y [1] == 3}, y [x], x]) [ [1]] 3 E^ (- (1/3) + x^3/3) (You dont need the Part (... [ 1 ]) here since Plot could handle it) Second you used VectorPlot. Webb27 sep. 2024 · We always lose the constant (term without a variable attached), when we take the derivative of a function. Which means we’re never going to get the constant back when we try to integrate our derivative. It’s lost forever. That is, unless we have an initial condition we can use to figure out what tha
