Find the approximate values of (i) `sin 1^(@)` (ii) `tan 2^(@)` (iii) `cos 1^(@)`.

Explanation

To find the approximate values of \( \sin 1^\circ \), \( \tan 2^\circ \), and \( \cos 1^\circ \), we can use the small angle approximations for trigonometric functions. For angles measured in degrees, we can convert them to radians since the small angle approximations are more straightforward in radians.

### Step-by-Step Solution:

1. **Calculate \( \sin 1^\circ \)**:
- Convert degrees to radians:
\[
1^\circ = \frac{1 \times \pi}{180} \text{ radians}
