Answer:
cot(θ) = 4/5
Step-by-step explanation:
In the polar/rectangular coordinate representation (x, y) ⇔ (r; θ), we know that ...
(x, y) = (r·cos(θ), r·sin(θ))
From the various trig definitions and identities, we also know that ...
cot(θ) = cos(θ)/sin(θ) = (x/r)/(y/r) = x/y
For the given (x, y) = (-4, -5), the cotangent is ...
cot(θ) = -4/-5 = 4/5

Infinity isn't actually a number - it's a concept that represents that the set of numbers goes on forever. As a result, you can't take the square root of infinity. However, you could state that as x approaches infinity (or rather, increase indefinitely), the square root of x also approaches infinity (again, increases indefinitely).
