If you're Your professor may have used r instead of alpha. Solving Differential Equations in R: Package deSolve. Journal of Statistical Software, 33, 4, February 2010  A. Where rhat is the unit vector in the radial direction. T = 1/freq; % period of voltage signal driving the circuit. It looks like you are trying to solve the second-order ODE r'' = - C rhat --------- |r|**2. El = T/2; % half length of period. Equations = { x0: 2*x0 + cos(3*x0), x1: sin(x0+x1) }. Into the original differential equation, one obtains the following so-called characteristic equation: m + a = 0, and therefore m = - a. If that title seems like a mouthful, it's because our studies so far have taught us how to solve just one very specific kind of ordinary differential equation (ODE). End_time = 5*T; % end time of simulation. Thus the solution of the differential equation has the form y = C * exp(-a * x) The constant C is necessary to comply with ..
