Mark the correct alternative in the following:
The value of tan 1° tan 2° tan 3° ... tan 89° is
tan 1° tan 2° tan 3° ... tan 89° = tan (90° - 89° ) tan(90° - 88° ) tan(90° - 87°) ... tan(90° - 46° ) tan 45° tan 46° …. tan 89°
= cot 89° cot 88° cot 87° ….. cot 46° tan 45° tan 46° ….. tan 89°
(∵ tan(90° - θ ) = cot θ )
= tan 45°
= 1
