als Konstante

Entferne die Konstante:

(a \cdot f)^{'} = a \cdot f^{'}

= \frac{1}{2} \frac{\partial}{\partial y} (e^{x} + e^{y})

Wende die Summen-/Differenzregel an:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{1}{2} (\frac{\partial}{\partial y} (e^{x}) + \frac{\partial}{\partial y} (e^{y}))

\frac{\partial}{\partial y} (e^{x}) = 0

\frac{\partial}{\partial y} (e^{y}) = e^{y}

= \frac{1}{2} (0 + e^{y})

Vereinfache

= \frac{1}{2} e^{y}

y^{^{''}} + 2 y^{^{'}} + y = 1, y (1) = 1, y^{^{'}} (1) = 0
