$\frac{2 \cot (x)}{1 + \cot^{2} (x)} = \frac{2 \cot (x)}{\csc^{2} (x)}$

Schritt 1

Subtrahiere $\frac{2 \cot (x)}{\csc^{2} (x)}$ von beiden Seiten der Gleichung.

$\frac{2 \cot (x)}{1 + \cot^{2} (x)} - \frac{2 \cot (x)}{\csc^{2} (x)} = 0$

Schritt 2

Vereinfache $\frac{2 \cot (x)}{1 + \cot^{2} (x)} - \frac{2 \cot (x)}{\csc^{2} (x)}$ .

Schritt 2.1

Wende den trigonometrischen Pythagoras an.

$\frac{2 \cot (x)}{\csc^{2} (x)} - \frac{2 \cot (x)}{\csc^{2} (x)} = 0$

Schritt 2.2

Subtrahiere $\frac{2 \cot (x)}{\csc^{2} (x)}$ von $\frac{2 \cot (x)}{\csc^{2} (x)}$ .

$0 = 0$
