E-Books →A Simple Approach to Trigonometry Proving Trigonometric Identities

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.
