Trigonometry: A Student's Companion

The word "trigonometry" originates from the Greek language"Tri" means three, "gonia" means angle, and "metry" means to measure. This book deals with the measurement of angles. It's specifically written for secondary students seeking to earn the International General Certificate of Secondary Education in Additional Mathematics or its equivalent. It relies heavily on illustrations to make concepts easy to understand, and all of the illustrations are scalable, vector-based graphics. E-book readers should take advantage of this feature. Concepts can be easily linked across chapters so you can develop an in-depth understanding of the material. Circular, sinusoidal, and quadrant perspectives are conceptually linked. The sine function around the four quadrants from a rotational aspect is explained, as well as the inverse of the sine. The unity circle and the relationship to the generated waveform is a major highlight, and all four quadrants are carefully and logically explained. The mathematical signs around the quadrants are also explored in detail. Get the tools, solutions, and examples you need to develop a more comprehensive understanding of the glorious world of Trigonometry.
