A Simple Approach to Trigonometry: Proving Trigonometric Identities

A Simple Approach to Trigonometry workbook focuses on trig identities. The majority of the exercises let you derive a variety of trig identities by following similar examples. If you get stuck, helpful hints in the back of the book help walk you through the solution. Other exercises include applications.

This self-teaching guide will teach you what you need to know on trigonometry from its basic to advance. The book will also enhance your knowledge of mathematics skills.

CONTENTS:
This workbook is conveniently divided up into 11 chapters so that students can focus on one trigonometry skill at a time. Learn more on…

converting between degrees and radians;

expressing sine, cosine, tangent, secant, cosecant, and cotangent as fractions by looking at right triangles;

solving for unknown sides and angles in 45°-45°-90° and 30°-60°-90° right triangles;

determining the sine, cosine, tangent, secant, cosecant, and cotangent of multiples of 30° and 45° up to 360° (working with both degrees and radians);

practice finding the reference angle for angles in Quadrants II, III, and IV;

finding the inverse trig functions;

applying the law of sines and the law of cosines to solve for unknown sides and angles in acute and obtuse triangles;

solving problems with trig identities (like the angle sum and difference formulas);

and solving algebraic equations that feature basic trig functions.
