Webb19 okt. 2024 · The equation y 2 + sin(y) = 2x 3 + C defines the general solution implicitly. Note: we cannot isolate for y to get an explicit general solution. For the particular solution, as usual, we use the initial condition y(1) = 0 and plug in x = 0 and y = 1 to the equation that defines the general solution.
