Question

If P(x, y) is the point on the unit circle defined by real number 0, then cot 0=

Answer 1

x/y

Explanation:

The question is badly worded, to the point of being impossible to answer as it is written.

We presume the given point (x, y) is (cos(θ), sin(θ)). The definition of cot(θ) is cos(θ)/sin(θ), so matches x/y with our assumed definitions of x and y.
