Evaluate : `tan35^0tan40^0tan45^0tan50^0tan55^0`

Explanation

To evaluate the expression \( \tan 35^\circ \tan 40^\circ \tan 45^\circ \tan 50^\circ \tan 55^\circ \), we can use the properties of trigonometric functions, particularly the relationship between tangent and cotangent.

### Step-by-Step Solution:

1. **Identify the angles**: We have the angles \( 35^\circ, 40^\circ, 45^\circ, 50^\circ, \) and \( 55^\circ \).

2. **Use the identity**: Recall that \( \tan(90^\circ - \theta) = \cot(\theta) \). This means:
- \( \tan 50^\circ = \cot 40^\circ \)
