Express the trigonometric ratios sin A, sec A and tan A in terms of cot A.

Explanation

To express the trigonometric ratios sin A, sec A, and tan A in terms of cot A, we can follow these steps:

### Step 1: Express sin A in terms of cot A
We know that:
\[ \sin A = \frac{1}{\sqrt{1 + \cot^2 A}} \]
This is derived from the Pythagorean identity where \(\sin^2 A + \cos^2 A = 1\) and the relationship between \(\cot A\) and \(\sin A\).
