Electrical Mathematics Made Easy with Comics
 |
Description
Book Introduction
A must-read book on electrical mathematics that explains the basics of mathematics and electricity!!
When studying basic electrical engineering, such as electrical circuits or electromagnetism, you may have had an experience where a lot of math was included and it was difficult to study.
This is because fields such as electrical engineering and electronic engineering are academic disciplines that cannot be studied without completely excluding mathematical knowledge.
Therefore, this book was written with the intention of helping to understand such difficult mathematical content.
The greatest feature of this book is that it explains the basics of mathematics and electricity in an easy-to-understand way through comics, allowing readers to learn the theory while having fun reading the comics.
To help readers understand how to solve practice problems, we used a cartoon character and presented the problem in a conversational format.
Therefore, we have provided detailed explanations to help readers understand the basic theory or to answer questions they may have while solving problems.
Additionally, when explaining the theory, unnecessary developments were avoided and only the core points were explained so that they could be understood practically.
Therefore, it will be an excellent guidebook not only for those who want to start from the basics in electrical engineering or electronics, but also for general readers.

Publisher's Review
Easy problem-solving format through conversation!!
To explain in detail how to apply the theory to a problem, we used a cartoon character to point out parts that readers might be curious about.
Additionally, the practice problems are explained in a conversational format to make the calculation process easier to understand.
Mathematical formulas explained in a friendly manner with diagrams and pictures!!
The process of developing mathematical formulas was explained one by one with pictures, as if the teacher was explaining it right next to me.
Formulas related to other theories have been supplemented with additional explanations to enhance mathematical application skills.
Official memorization method, easily memorize through the "Check" corner!!
Formulas that must be remembered and memorized are presented once more through the "Check" corner, and methods for memorizing the formulas are provided during the explanation process, making it easier for readers to remember.
