This module introduces core mathematical tools that are directly applied in electrical engineering analysis, design, and problem-solving. The emphasis is on using mathematics as an engineering tool, not as abstract theory. Each topic in the first unit is linked to real electrical engineering applications that students encounter in circuits, machines, electronics, power systems, and control.

1.Students learn that elementary functions describe how electrical quantities vary with time, frequency, and system parameters.

2.Derivatives are essential for understanding how electrical quantities change.

3.Integration allows students to quantify energy, charge, and total system response.

4.Vectors enable students to visualize and analyze multi-directional electrical phenomena.

5.Matrices make it possible to analyze large and complex electrical systems accurately and efficiently.
