and Inequalities, Geometry in the Cartesian System, Functions and Function
Notation, Transformations of Graphs, Combining Functions, Inverse Functions,
Angles and Arcs, Trigonometric Functions of Acute Angles, Trigonometric
Functions of Any Angle, Trigonometric Functions of Real Numbers, Graphs of the
Sine and Cosine Functions, Trigonometric Functions, Simple Harmonic Motion,
Verifying Trigonometric Identities, Sum and Difference Identities, The
Double-Angle and Half-Angle Identities, Conversion Identities, Inverse
Trigonometric Functions and Trigonometric Equations.

This note covers functions
and special angles, Graphs of trig functions, Inverse trigonometric functions,
Key angle formulas, Trigonometric identities and equations, Solving an oblique
triangle, Polar coordinates, Polar functions and vectors.

This note explains the following topics:
Basic Trigonometry, Applications to complex numbers,
Applications to complex Geometry, Application to Planar Geometry, 3D
Geometry and Trigonometric Substitution.

This book
was written with those teachers and students in mind who are engaged in
trigonometric ideas in courses ranging from geometry and second-year
algebra to trigonometry and pre-calculus. The lessons contain historical
and cultural context, as well as developing traditional concepts and
skills.
