(\partial}{\partial t}(\frac{sin(t))/t)

Lösung

\frac{\partial}{\partial t} (\frac{sin ( t )}{t})

\frac{t cos ( t ) - sin ( t )}{t ^{2}}

Schritte zur Lösung

\frac{\partial}{\partial t} (\frac{sin ( t )}{t})

Wende die Quotientenregel an:

(\frac{f}{g})^{'} = \frac{f ^{'} \cdot g - g ^{'} \cdot f}{g ^{2}}

= \frac{\frac{\partial}{\partial t} ( sin ( t ) ) t - \frac{\partial}{\partial t} ( t ) sin ( t )}{t ^{2}}

\frac{\partial}{\partial t} (sin (t)) = cos (t)

\frac{\partial}{\partial t} (t) = 1

= \frac{cos ( t ) t - 1 \cdot sin ( t )}{t ^{2}}

Vereinfache

= \frac{t cos ( t ) - sin ( t )}{t ^{2}}

\frac{\partial}{\partial x} (tan (4 x))

\frac{d}{d t} (t^{2} - t)

x y^{^{'}} + 3 y = 5 x^{2}
