I know how to do it with a diff equation of first order, but it does not work with this one. Summary of Techniques for Solving Second Order Differential Equations. Lecture 12: How to solve second order differential equations. For what values of constants a and m does y = x^a * e^mx satisfy the ordinary differential equation y'' + 2x^(-1)y' - 2y = 0 Find the solution of this Ordinary Differential Equation satisfying the initial conditions y(1) = 1 and y'(1) = 0 For the first part I keep getting -2, and 2 for a and m respectively, but then it doesn't follow through for the rest of the problem so I must be. Autonomous equation. Differential Equation Calculator. y″ − y = 0. I want to solve 2nd order differential equations without using scipy. Quadratic equation is a second order polynomial with 3 coefficients - a, b, c.
