Understanding Mathematical Functions and Their Properties
Functions
A function, as defined by Laplace, is a law that associates each value of the independent variable x with a value of the dependent variable y. This correspondence can be written as:
A function is said to be injective if each element of the domain (set A, represented by x) maps to a unique element of the codomain (set B, represented by y). This is also known as a one-to-one correspondence.
A function is surjective if every element of the codomain (B) is an image of an element in the domain

Types of Costs
We analyze various types of costs, including variable and fixed costs, and how they are incorporated into different costing systems. The primary systems we’ll explore are:
- Full Costing
- Direct Costing
- Rational Imputation
Full Costing
Definition
Full costing, also known as absorption costing, incorporates all costs related to production into the cost of the products. The total cost of production for a given period is calculated as follows:
- Consumption of Raw Materials

Statistical Data from Quantitative Variables
We use statistical methods to describe data derived from quantitative variables.
Primitive Table of Student Heights
Table 5.1 shows the raw, unorganized height data (in cm) of a group of students. This type of table, with numerically unorganized elements, is called a primitive table: 166, 160, 150, 162, 160, 165, 160, 167, 164, 160, 162, 161, 168, 163, 156, 173, 160, 155, 164, 168, 155, 152, 163, 160, 155, 155, 159, 151, 170, 164, 154, 161, 156, 172, 153,

Curtain Positions and Reporting
In entry/exit areas, the optimal curtain position is typically in the center, specifically sectors X or a point on line X-O.
Current Status Reporting
YY designates the current status of the recipient. In an exit curtain, the leader at point O should form the curtain up.
“Current Status” (YY) refers to the recipient’s current status.
