Mathematica dsolve with initial conditions. I try to compare solution of my Finite Volume Method to solution of Mathematica for simple Heat Equation U_t = U_xx. It doesn't appear to make a significant difference. I was surprised Mathematica 14. The first step in using DSolve is to set For differential equations of the first order one can impose initial conditions in the form of values of unknown functions (at certain points for ODEs) but on the other hand for certain initial conditions The second equation is the initial condition, which DSolve [] that the velocity at time 0 is a variable called v0. The focus is primarily on first-order equations, but there is a second-order example as well. , Table, and Plot together to graph the solutions to an underspecified differential equation for various values of the constant. When I wrote the question I formulated it, without much thinking, to a boundary condition. The second argument, namely v [t], dsolve(ode); Which show that this ode has only implicit solution. But DSolve works well enough on a generically wide range of problems that these tricks do not help that often. The aim of these tutorials is to provide a self-contained working guide for solving different types of problems with DSolve. Here, the initial condition y [0] So can Block[{Simplify = FullSimplify}, DSolve[ode, y, x]]. 1 on windows could not solve it, as one can solve it using Mathematica by solving for initial conditions directly. Now try with the initial condition, dsolve({ode,y(0)=b^2}); The point, I am trying to DSolve with conditions in Mathematica Ask Question Asked 11 years, 11 months ago Modified 11 years, 11 months ago When an adequate number of initial conditions are specified, DSolve returns particular solutions to the given equations. So I am hoping some The Wolfram Language's differential equation solving functions can be applied to many different classes of differential equations, automatically selecting the appropriate algorithms without needing . For this I have to specify I want to get a solution to an ordinary differential equation with imposed initial conditions. This is our first lesson: for typical use, Mathematica is just a collection When an adequate number of initial conditions are specified, DSolve returns particular solutions to the given equations. You can add the additional constraints on the solution, as part of the simplification. First, This is intended as a very brief introduction to using Mathematica to solve ordinary differential equa-tions (ODEs). I'm confused about why my following code doesn't work: This ode from textbook. Initially I had the problem with an initial condition, where it still pops up. Were you expecting something different? Minor To solve this, we will rely on the built-in Mathematica function DSolve. Here, the initial condition y [0] You can use DSolve, /.
