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

There is no such real number!
a+b=-5
ab=625
a=-b-5
(-b-5)*b=625
-b^2-5b=625
b^2+5b+625=0
b=-5+-sqrt(25-2500)
This resulting in b as a complex number which means in the real numbers there is no such solutions!
