Symbolic and numerical equation solving and root finding, differential equations, recurrence and functional equations, systems of equations, linear systems, visualization of solutions... Wolfram Community threads about Equation Solving. For example, I input the following into wolfram but it does not show me the step by step option as opposed to just inputting 1 linear ODE. You can choose the derivative function using the drop-down menu and the initial guess for the algorithm. It only takes a minute to sign up. An ordinary differential equation (ODE) contains one or more derivatives of a dependent variable, y, with respect to a single independent variable, t, usually referred to as time.The notation used here for representing derivatives of y with respect to t is y ' for a first derivative, y ' ' for a second derivative, and so on. The tautochrone problem requires finding the curve down which a bead placed anywhere will fall to the bottom in the same amount of time. I've been trying to solve a system of ODE's with mathematica, which is a master equation of a hierarchically organized tissue model, where I want to quantify the number of cells at level 'k' with 'm' Stack Exchange Network.
