Question

plz fast solve with explain

Answer 1

Heya mate, Here is ur answer


Cot 12° × cot 38° × cot 52° × cot 60° × cot 78°


$<b><u>Rearranging the terms </u></b>$


Cot 12° × cot 78° × cot 38°× cot 52° × cot 60°


= cot 12° × cot (90-12°) × cot 38°× cot(90-38°)× cot 60°


= cot 12° × Tan 12° × cot 38°× Tan 38° × cot 60°


$= \cot(12) \times \frac{1}{ \cot(12) } \times \cot(38) \times \frac{1}{ \cot(38) } \times \cot(60)$


= Cot 60°


$= \frac{1}{ \sqrt{3} }$

Answer 2

Cot12° × Cot38° × Cot 52° × Cot 60° × Cot78°




Cot12° × Cot78° × Cot38° × Cot52° × Cot 60°




Cot 12° × Cot ( 90 - 12° ) × Cot38° × Cot(90-38° ) × Cot60° .



Cot12° × Tan12° × Cot38° × Tan38° × Cot60°



1/ Tan12° × Tan12° × 1/ Tan38° × Tan38° × Cot60°


1 × 1/√3



1/✓3.
