4ln(x)dx-xsec^2(y)dy=0

Lösung

4 ln (x) d x - x sec^{2} (y) d y = 0

y = arctan (2 ln^{2} (x) + c_{1}) + πn

Schritte zur Lösung

4 ln (x) d x - x sec^{2} (y) d y = 0

Solve separable ODE:

y = arctan (2 ln^{2} (x) + c_{1}) + πn

y = arctan (2 ln^{2} (x) + c_{1}) + πn

\frac{d y}{d x} 2 x y = 1

\frac{d Q}{d x} = 15 - 3 \frac{Q}{400}

e^{t} y^{^{'}} = (1 + y^{2}) t

x^{2} y^{^{'}} = y^{2}, y (1) = - 1

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