Answer: 1
Step-by-step explanation:
tan1°= cot89°
tan2°= cot 88°..........tan44°= cot 46°
We know, tanA cotA= 1
Therefore,
Tan1° tan2° tan3°......tan45°.......tan89°
= Cot89° cot88° cot87°..........cot46° tan45° tan46° ......tan89°
= 1 × tan45°. [Since, tan45°=1]
= 1×1
=1
Hope this answer helps you....
