Mathematics is the language of engineering and a compulsory subject in worldwide engineering education. So as engineering students, it is mandatory to study Mathematics and learn Mathematical calculations meticulously. In engineering, there are several branches such as computer engineering, electrical and electronic engineering, mechanical engineering, communication engineering and civil engineering and each branch has a different study set focused on the significance of Mathematics. Mathematics provides the analytical and problem-solving tools necessary for engineers to design, analyze and optimize systems, ensuring that they meet safety, efficiency and performance requirements. Without mathematics, engineers would struggle to design effective control systems, leading to inefficiencies and instability in processes. This book provides the easiest and comfortable techniques to the students to learn mathematical calculations effortlessly and independently at home. Moreover, the necessary formulas have been included here with the very beginning of this book so that students can get a complete idea of calculations without the help of other study materials.
