Ordinary Differential Equations (ODEs) Made Easy. How about we model the position of a spring with resting initial position and velocity, and forcing function sin(2 t): y”(t) + y(t) = sin(2t), y(0) = 0, y‘(0) = 0. Three methods are provided here for solving this ODE. An example of an ODE that models the angle of a pendulum over time is y“(t). First, Second and higher order Differential Equations. Shows step by step solutions for some Differential Equations such as separable, exact, Includes Slope Fields, Euler method, Runge Kutta, Wronskian, LaPlace transform, system of Differential Equations, Bernoulli DE, (non) homogeneous linear systems with constant coefficient, Exact DE, shows Integrating Factors, Separable DE and . Includes Slope Fields, Euler method, Runge Kutta, Wronskian, LaPlace transform, system of Differential Equations, Bernoulli DE, (non) homogeneous linear systems with constant coefficient, Exact DE, shows Integrating Factors, Separable DE and much more. Ideal for quick review and homework check in Differential Equation/Calculus classes. Easy to use.
