Answer:
7.595754113 or 2 + √2 + √3 + √6
Step-by-step explanation:
Best Answer: cot(15/2)°
= cos(15/2)° / sin(15/2)°
= 2cos^2 (15/2)° / 2sin(15/2)° cos(15/2)°
= (1 + cos15°)/sin15°
Plugging cos15° = (1/4) (√6 + √2) and sin15° = (1/4) (√6 - √2)
= [1 + (1/4) (√6 + √2)] / [(1/4) (√6 - √2)]
=2 + √2 + √3 + √6
