Differential Equations after Calc 2 (self. How do you like me now (that is what the differential equation would say in response to your shock)!. In mathematics, the power series method is used to seek a power series solution to certain differential equations. We also discuss more about initial conditions and how they determine the first two coefficients in the power series solution. For this, we need only compute Fpolynomial of degree less than N+ 1 (when k= 0) or N(otherwise). The user WILL HAVE TO ALTER CODE for each differential equation since multiple inputs into a function are done. In other words, the radius of convergence of the series solution is at least as big as the minimum of the radii of convergence of p(t) and q(t). Differential Equations.
