The exact values of the cotangent and the cosine of the angle are
and
, respectively.
According to the information given, the angle resides in the <em>first</em> quadrant of the Cartesian plane. Hence, the cosine and the cotangent of the angle are also positive.
By trigonometry we remember the concepts of sine, cotangent and cosine:
(1)
(2)
(3)
Where
.
If we know that
and
, then the cotangent and the cosine of the angle are, respectively:
