Learn how to solve problems step by step online. (tan(x)^2+1)/cot(x)=tan(x)/(cos(x)^2). Ausgehend von der linken Seite (LHS) der Identität. Applying the trigonometric identity: 1+\tan\left(\theta \right)^2 = \sec\left(\theta \right)^2. Applying the trigonometric identity: \cot\left(\theta \right) = \frac{\cos\left(\theta \right)}{\sin\left(\theta \right)}. Wenden Sie die Formel an: \frac{a}{\frac{b}{c}}=\frac{ac}{b}, wobei a=\sec\left(x\right)^2, b=\cos\left(x\right), c=\sin\left(x\right), a/b/c=\frac{\sec\left(x\right)^2}{\frac{\cos\left(x\right)}{\sin\left(x\right)}} und b/c=\frac{\cos\left(x\right)}{\sin\left(x\right)}.
