SUMMARY
The discussion focuses on solving the trigonometric expression cot(Arctan(-√(5)/2)). It establishes that cot(x) is the reciprocal of tan(x), leading to the conclusion that cot(Arctan(-√(5)/2)) equals 1/tan(Arctan(-√(5)/2)). The value of tan(Arctan(-√(5)/2)) is directly -√(5)/2, thus simplifying the expression to -2/√5.
