WebNov 16, 2024 · The (implicit) solution to an exact differential equation is then. Ψ(x,y) = c (4) (4) Ψ ( x, y) = c. Well, it’s the solution provided we can find Ψ(x,y) Ψ ( x, y) anyway. Therefore, once we have the function we can always just jump straight to (4) (4) to get an implicit solution to our differential equation. WebOct 29, 2011 · Explicit solution is a solution where the dependent variable can be separated. For example, is explicit because if y is dependent, I can rewrite it as and my y has been separated.
