Second order differential equation solver

    • What is the solution of second order equation?

      Take any equation with second order differential equation Let us assume dy/dx as an variable r Substitute the variable r in the given equation It will form a binomial equation Solve the equation and find its factors Find the value of y

    • What does it mean to solve a differential equation?

      A differential equation is a mathematical equation that involves variables like x or y, as well as the rate at which those variables change. Differential equations are special because the solution of a differential equation is itself a function instead of a number.

    • What is second order differential?

      A second order differential equation is an equation involving the unknown function y, its derivatives y' and y'', and the variable x. We will only consider explicit differential equations of the form, Nonlinear Equations.

    • How to solve a differential equation?

      Put the differential equation in the correct initial form, (1) (1). Find the integrating factor, μ(t) μ ( t), using (10) (10). Multiply everything in the differential equation by μ(t) μ ( t) and verify that the left side becomes the product rule (μ(t)y(t))′ ( μ ( t) y ( t)) ′ ... Integrate both sides, make sure you properly deal with the constant of integration. Solve for the solution y(t) y ( t).
