A quadrant is the area that is divided into the x and y axes
The quadrants in which tan
and cot
are positive are I and III
<h3>How to determine the quadrants</h3>
The tangent of an angle is calculated as:

While the cotangent of the angle is calculated as:

The above equations mean that:
For the tangent and cotangent of an angle to be positive, then the sine and the cosine of the angle must have the same sign.
- In the first quadrant, the sine and the cosine angles are positive.
- In the third quadrant, the sine and the cosine angles are negative.
Hence, the quadrants in which tan
and cot
are positive are I and III

.

The square of
is 10.

Factor
. Rewrite the square root of the product
as the product of square roots
.

Multiply
and
to get 2.

Multiply -2 and 2 to get -4.

The square of
is 2.

Add 10 and 2 to get 12.

- Here, b & c are integers where
