-2x-9y^2(dy)/(dx)=0

Lösung

- 2 x - 9 y^{2} \frac{d y}{d x} = 0

y = 3 - \frac{x ^{2}}{3} + c_{1}

Schritte zur Lösung

- 2 x - 9 y^{2} \frac{d y}{d x} = 0

Solve separable ODE:

y = 3 - \frac{x ^{2}}{3} + c_{1}

y = 3 - \frac{x ^{2}}{3} + c_{1}

y^{^{'}} - 2 y = - 5

y^{3} \cdot \frac{d y}{y ^{4}} = 4 x^{2} - 8 x^{2} d x

\frac{y ^{^{'}}}{x} + 2 y = 4

\frac{d x}{d y} + 3 x = 25

y^{^{'}} + \frac{y}{5} = 3, y (- 3) = 0
