## Description de l’éditeur

Studying Maths is always difficult and takes time, and even you try harder and harder, you can not even know all of the aspects of the Mathematics World.

However, there is a branch that is considered an interesting part to study in maths. That is Trigonometry-studying relationships between side lengths and angles of triangles. It's hard, sometimes easy. This book provides you with methods to solve trigonometry problems and it is essential especially for students in school. It provides ample practice for developing fluency in very fundamental trigonometry skills. Every problem can be answered without a calculator, which is very helpful for students who aren't allowed to use a calculator. This is the case in some trig and physics courses, as well as some standardized exams (like the MCAT).

This workbook is conveniently divided up into 11 chapters so that students can focus on one trigonometry skill at a time. Skills include the following:

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

solving for unknown sides and angles in 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.

Let's practice maths.
