In Unit Circle, we know that x-term = cos and y-term = sin


\large \boxed{(x,y) = (cos \theta , sin \theta)}

Recall the cotangent ratio:


\large \boxed{cot \theta = (cos \theta)/(sin \theta) }

Because cotangent is reciprocal of tangent which is sin/tan so cotangent is 1/(sin/cos) = cos/sin.

Substitute the point in.


\large{cot \theta = ( - 5)/( - 12 ) \longrightarrow (5)/(12) }

Answer

  • cot theta = 5/12

Let me know if you have any doubts!
