Deduction is a term used as inference to a known and validated principle. This is when you analyze points through logic from a given set of rules and conditions. You relate how the situation may conform to the rules. Thus. there is no wrong deduction. If you analyze it to be true, then that must be definitely correct. Therefore, the answer is letter B. What must be true.
(x+6)(x-6) would be the factored form
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
