What is analytical and numerical solution? An analytical solution involves framing the problem in a well-understood form and calculating the exact solution. A numerical solution means making guesses at the solution and testing whether the problem is solved well enough to stop. What is the difference between analytical and numerical methods? Analytical is exact; numerical is approximate. For example, some differential equations cannot be solved exactly (analytic or closed form solution) and we must rely on numerical techniques to solve them. Numerical methods use exact algorithms to present numerical solutions to mathematical problems. What does solve analytically in math mean?...
