HELP, Prove: (cos(x))/(sin(x)tan(x))=cot^2x
Mice21 [21]

Answer:

Steps shown below

Step-by-step explanation:

We will simplify this using definitions and identities. Let's start.

\frac{cos(x)}{sin(x)tan(x)}

Using tanx=\frac{sinx}{cosx}, we have:

\frac{cos(x)}{sin(x)\frac{sin(x)}{cos(x)}}\\=\frac{cos^2(x)}{sin^2(x)}

Using cot(x)=\frac{cos(x)}{sin(x)}, we have:

\frac{cos^2(x)}{sin^2(x)}\\=cot^2(x)

Hence, proved.
