Question

If p(x,y) is the point on the unit circle defined by real number theta, then cot theta= _____ A. 1/y B. 1/x C. x/y D. y/x

Answer 1

C. x/y
..................

Answer 2

Explanation:

Alright, lets get started.

Please refer the diagram I have attached.

As per SOH CAH TOA,

tan θ =
`(opposite)/(adjacent)`

so, cot θ =
`(adjacent)/(opposite)`

cot θ =
`(x)/(y)`

hence the answer is C:
`(x)/(y)` : Answer
