Answer:</h2>
The type of reasoning which starts with a given set of rules and conditions to determine what must be true is:
Deductive Reasoning.
<h2>
Step-by-step explanation:</h2>
Deductive Reasoning--
It is a logical reasoning that starts with a general set of premises or statements and reach to a specific conclusion.
It is different from the inductive reasoning in the way that the inductive reasoning starts with a set of specific set of rules and reach to a general conclusion.

Hello!</h2>
The answer is: 
<h2>
Why?</h2>
Domain and range of trigonometric functions are already calculated, so let's discard one by one in order to find the correct answer.
The range is where the function can exist in the vertical axis when we assign values to the variable.
First:
: Incorrect, it does include 0.4 since the cosine range goes from -1 to 1 (-1 ≤ y ≤ 1)
Second:
: Incorrect, it also does include 0.4 since the cotangent range goes from is all the real numbers.
Third:
: Correct, the cosecant function is all the real numbers without the numbers included between -1 and 1 (y≤-1 or y≥1).
Fourth:
: Incorrect, the sine function range is equal to the cosine function range (-1 ≤ y ≤ 1).

Answer:
Step-by-step explanation:
Given

Required
Find 
First, calculate 
--- angle on a straight line
So, we have:
Collect like terms
Next, calculate PQR
So, we have:
Collect like terms
So, PRO is calculated as:
--- angles in a triangle
So, we have:
Collect like terms
