https://doi.org/10.1007/978-3-642-47472-9ear differential equation with variable coefficients cannot be solved by the use of exponential functions. We did, however, solve a special equation with variable coefficients, the Cauchy equation, by assuming a simple power solution.只有 发表于 2025-3-24 02:27:59
https://doi.org/10.1007/978-3-642-49873-2larly useful in solving nonhomogeneous equations that result when modeling systems involving discontinuous, periodic input functions, such as was done with the Fourier series in Chapter 1. It is not necessary, however, when using Laplace transforms that a homogeneous solution and a particular soluti吼叫 发表于 2025-3-24 08:27:26
