Anwendung der trigonometrischen Identität: \cot\left(\theta \right)^n=\frac{\cos\left(\theta \right)^n}{\sin\left(\theta \right)^n}, wobei n=2. Wenden Sie die Formel an: \frac{a}{b}\frac{c}{f}=\frac{ac}{bf}, wobei a=2\sin\left(x\right), b=\cos\left(x\right), c=\cos\left(x\right)^2, a/b=\frac{2\sin\left(x\right)}{\cos\left(x\right)}, f=\sin\left(x\right)^2, c/f=\frac{\cos\left(x\right)^2}{\sin\left(x\right)^2} und a/bc/f=\frac{2\sin\left(x\right)}{\cos\left(x\right)}\frac{\cos\left(x\right)^2}{\sin\left(x\right)^2}. Wenden Sie die Formel an: \frac{a^n}{a}=a^{\left(n-1\right)}, wobei a^n/a=\frac{2\sin\left(x\right)\cos\left(x\right)^2}{\cos\left(x\right)\sin\left(x\right)^2}, a^n=\cos\left(x\right)^2, a=\cos\left(x\right) und n=2.
