Trigonometry and Single Phase AC Generation 

This is a beginner-friendly textbook designed to build the math and electrical theory skills essential for electricians. It starts with foundational trigonometry concepts before applying these to vector math and AC generation principles.The book is organized into three main parts:<ul><li>Trigonometry — covers types of angles, triangles, Pythagoras’ theorem, naming triangle sides, and basic trig functions (sine, cosine, tangent). These concepts help explain electrical impedance and power triangles.</li><li>Vectors — introduces vectors as quantities with magnitude and direction, explains polar and rectangular forms, shows how to convert between them, and teaches vector addition needed for AC circuit analysis.</li><li>Single Phase AC Generation — explains electromagnetic induction, compares simple and practical alternators, shows how sine waves are produced, and analyzes waveforms including RMS values, frequency, and rotation speed.</li></ul>The book uses clear explanations, practical examples, and step-by-step approaches to make complex concepts accessible for trade learners.

This eBook teaches trigonometry and vectors—right triangles, Pythagoras, and vector addition—and applies them to electrical concepts such as AC generation, electromagnetic induction, alternator components, and sine wave analysis.
