\frac{2 l ( cos ( θ ) x ( θ ) + sin ( θ ) \frac{d}{d θ} ( x ( θ ) ) ) - l ^{2} sin ( 2 θ ) - 2 x ( θ ) \frac{d}{d θ} ( x ( θ ) )}{2 l ^{2} - l ^{2} sin ^{2} ( θ ) + 2 l sin ( θ ) x ( θ ) - x ( θ ) ^{2}} + l sin (θ)

Schritte zur Lösung

\frac{d}{d θ} (l^{2} - (l sin (θ) - x (θ))^{2} - l cos (θ))

Wende die Summen-/Differenzregel an:

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

= \frac{d}{d θ} (l^{2} - (l sin (θ) - x (θ))^{2}) - \frac{d}{d θ} (l cos (θ))

\frac{d}{d θ} (l^{2} - (l sin (θ) - x (θ))^{2}) = \frac{2 l ( cos ( θ ) x ( θ ) + sin ( θ ) \frac{d}{d θ} ( x ( θ ) ) ) - l ^{2} sin ( 2 θ ) - 2 x ( θ ) \frac{d}{d θ} ( x ( θ ) )}{2 l ^{2} - l ^{2} sin ^{2} ( θ ) + 2 l sin ( θ ) x ( θ ) - x ( θ ) ^{2}}

\frac{d}{d θ} (l cos (θ)) = - l sin (θ)

= \frac{2 l ( cos ( θ ) x ( θ ) + sin ( θ ) \frac{d}{d θ} ( x ( θ ) ) ) - l ^{2} sin ( 2 θ ) - 2 x ( θ ) \frac{d}{d θ} ( x ( θ ) )}{2 l ^{2} - l ^{2} sin ^{2} ( θ ) + 2 l sin ( θ ) x ( θ ) - x ( θ ) ^{2}} - (- l sin (θ))

Vereinfache

= \frac{2 l ( cos ( θ ) x ( θ ) + sin ( θ ) \frac{d}{d θ} ( x ( θ ) ) ) - l ^{2} sin ( 2 θ ) - 2 x ( θ ) \frac{d}{d θ} ( x ( θ ) )}{2 l ^{2} - l ^{2} sin ^{2} ( θ ) + 2 l sin ( θ ) x ( θ ) - x ( θ ) ^{2}} + l sin (θ)

\frac{d y}{d x} = \frac{4 x}{3 y}
