Our basis for this equality is the pythagorean theorems of trigonometry. There are three equations for the pythagorean theorems. These are:
sin²x + cos²x =1
1 + tan²x = sec² x
1 + cot² x = csc² x
These are all derived from circle geometry on the cartesian plane. Now, the useful trigonometric property to be used is the third one. Rearranging this, we come up with
cot²x - csc²x = -1
This coincided with the given equation. Therefore, this is true. This is because it is already established from the pythagorean theorems.
Functions are used to represent tables and equations
- The function that represents the number of imports is f(x) = 2x
- The function that represents the number of exports is f(x) = 2 + x
<h3>How to determine the import function</h3>
From the table, we can see that the values of the import is twice the number of months
This is represented as:
y = 2x
Rewrite as a function
f(x) = 2x
Hence, the function that represents the number of imports is f(x) = 2x
<h3>How to determine the export function</h3>
From the table, we can see that the values of the export is two more than the number of months
This is represented as:
y = 2 + x
Rewrite as a function
f(x) = 2 + x
Hence, the function that represents the number of exports is f(x) = 2 + x

Answer: 
Step-by-step explanation:
Given:
A town's population has been growing linearly. In 2003, the population was 35000, and the population has been growing by 1200 (constant rate of change) people each year.
The equation of a line is given by :-
, where m is the slope ( constant rate of change) and c is the initial value of the function.
From the given statement , we have the equation for the population x years after 2003 :-
