Hey there !!


Find the value :-


tan 1° tan 2° tan 3° ...... tan 89° .



Solution :-


= tan 1° tan 2° tan 3° ...... tan 89° .


= tan 1° tan 2° ... tan 44° tan 45° tan 46° ... tan 88° tan 89° .


= ( tan 1° • tan 89° )( tan 2° • tan 88° ) .... ( tan 44° • tan 46° ) • tan 45° .


= { tan 1° • tan( 90° - 1° )} • { tan 2° • tan( 90° - 2° )} .... tan 44° • tan( 90° - 44° )} • tan 45° .


= ( tan 1° • cot 1° )( tan 2° • cot 2° )....( tan 44° • cot 44° ) • 1 .

[ °•° tan( 90° - ∅ ) = cot ∅ and tan 45° = 1 ]


= 1 × 1 × .... × 1 × 1 .


 \boxed{ \boxed{ \bf = 1. }}



✔✔ Hence, it is solved ✅✅.
