together with the techniques needed to determine if a partial differential equation is well-posed or what the "natural" boundary conditions are. Subsequent sections focus on exact and approximate analytical solution techniques for differential equations, along with numerical methods for ordinary and partia...
1)second order differential equation二阶微分方程 1.The existence of positive homoclinic orbits is obtained by the variational approach for a class of thesecond order differential equations-α(x)u+β(x)u2+γ(x)u3=0,where the coefficient functions α(x),β(x),γ(x) satisfy xα′(x)≥0,...
We can solve a second order differential equation of the type: d2ydx2 + P(x)dydx + Q(x)y = f(x) where P(x), Q(x) and f(x) are functions of x, by using: Undetermined Coefficients which only works when f(x) is a polynomial, exponential, sine, cosine or a linear combination...
