y^'=y(7-y)-49/4 ,y(0)=a

Lösung

y^{^{'}} = y (7 - y) - \frac{49}{4}, y (0) = a

y = \frac{7 a t}{2 a t - 7 t + 2} - \frac{49 t}{2 ( 2 a t - 7 t + 2 )} + \frac{2 a}{2 a t - 7 t + 2}

Schritte zur Lösung

y^{'} (t) = y (7 - y) - \frac{49}{4}

Solve separable ODE:

y = \frac{7 a t}{2 a t - 7 t + 2} - \frac{49 t}{2 ( 2 a t - 7 t + 2 )} + \frac{2 a}{2 a t - 7 t + 2}

y = \frac{7 a t}{2 a t - 7 t + 2} - \frac{49 t}{2 ( 2 a t - 7 t + 2 )} + \frac{2 a}{2 a t - 7 t + 2}

y^{^{'}} = \frac{( 3 x ^{4} + y ^{4} )}{x y ^{3}}
