This lecture note talks about topics not
usually covered in trigonometry. These include such topics as the Pythagorean
theorem, proof by contradiction, limits, and proof by induction. As well as
giving a geometric basis for many of the relationships of trigonometry.

This book contains
all the propositions usually included under the head of Spherical Trigonometry,
together with a large collection of examples for exercise.

Elementary trigonometry
is a book written by mathematicians H. S. Hall and S. R. Knight. This book
covers all the parts of Elementary Trigonometry which can conveniently be
treated without the use of infinite series and imaginary quantities. The
chapters have been subdivided into short sections, and the examples to
illustrate each section have been very carefully selected and arranged, the
earlier ones being easy enough for any reader to whom the subject is new, while
the later ones, and the Miscellaneous Examples scattered throughout the book,
will furnish sufficient practice for those who intend to pursue the subject
further as part of a mathematical education.

This book
covers elementary trigonometry. It is suitable for a one-semester course at the
college level, though it could also be used in high schools. The prerequisites
are high school algebra and geometry.

This note
contains the following subtopics: Exponential and
Logarithmic Functions, Trigonometric Functions, Circular Functions and Their
Graphs, Trigometric Identities and Equations.

This note explains the following topics:
Annual Temperature Cycles, Trigonometric Functions, Trigonometric Models:
Vertical Shift and Amplitude, Frequency and Period, Phase Shift, Examples, Phase
Shift of Half a Period, Equivalent Sine and Cosine Models.

These notes are more of an introduction and guide than a full course.
Topics covered includes: Applications of trigonometry, What is trigonometry?,
Background on geometry, Angle measurement, Chords, Sines, Cosines, Tangents and
slope, The trigonometry of right triangles, The trigonometric functions and
their inverses, Computing trigonometric functions, The trigonometry of oblique
triangles, Demonstrations of the laws of sines and cosines, Area of a triangle,
Ptolemy’s sum and difference formulas and Summary of trigonometric formulas.
