WebSolving Riccati equations is considerably more difficult than solving linear ODEs. Here is a simple Riccati equation for which the solution is available in closed form: Any Riccati equation can be transformed to a second-order linear ODE. If the latter can be solved explicitly, then a solution for the Riccati equation can be derived. http://www2.gcc.edu/dept/math/faculty/BancroftED/teaching/handouts/first_order_linear_exact_ODEs.pdf WebMar 24, 2024 · remain finite at (), then the point is ordinary.Case (b): If either diverges no more rapidly than or diverges no more rapidly than , then the point is a regular singular point.Case (c): Otherwise, the point is an irregular singular point.
