 Trigonometry by National Open University Of NigeriaNational Open University Of
NigeriaPDF  131 Pages  EnglishThe course aims at giving you a good understanding of trigonometry and
its applications in everyday life. Topics covered includes: Trigonometric
ratios, Bearings, Inverse of trigonometric ratios, Graph of trigonometric
ratios, Trigonometric Identities and trigonometric equations , Solution of
triangle and Angles of elevation and depression.
 Elements of Plane TrigonometryHugh BlackburnOnline  143 Pages  EnglishFirst Chapter explains Newton's
Method of Limits to the mensuration of circular arcs and areas. The succeeding
Chapters are devoted to an exposition of the nature of the Trigonometrical
ratios, and to the demonstration by geometrical constructions of the principal
propositions required for the Solution of Triangles.
 Notes from TrigonometrySteven ButlerPDF  183 Pages  EnglishThis 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.
 Plane trigonometry and numerical computationJohn Wesley Young and
Frank Millett MorganOnline  146 Pages  EnglishThe first six chapters of this book give the
essentials of a course in numerical trigonometry and logarithmic computation.
The remainder of the theory usually given in the longer courses is contained in
the last two chapters.
  Elementary trigonometryH. S. Hall and S. R. KnightOnline  472 Pages  EnglishElementary 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.
 Trigonometry TextBook PDF 180PMichael CorralPDF  180 Pages  English This book
covers elementary trigonometry. It is suitable for a onesemester course at the
college level, though it could also be used in high schools. The prerequisites
are high school algebra and geometry.
 Lecture Notes Trigonometry (PDF 88P)Andrew KoinesPDF  88 Pages  EnglishThis note is focused on the
following subtopics: Trigonometric Functions, Acute
Angles and Right Angles, Radian Measure and Circular Functions, Graphs of the
Trigonometric Functions, Trigonometric Identities, Inverse Trig Functions and
Trig Equations, Applications of Trigonometry and Vectors.
 Lecture Notes on Trigonometry Lial, Hornsby, ShcneiderOnline  NA Pages  EnglishThis note
contains the following subtopics: Exponential and
Logarithmic Functions, Trigonometric Functions, Circular Functions and Their
Graphs, Trigometric Identities and Equations.
  Dave's Short Trigonometry CourseDavid
E. JoyceOnline  NA Pages  EnglishThese 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.
 Lecture Notes on Algebra and TrigonometryJerry
Alan VeehPDF  86 Pages  EnglishThe objective of a large part of mathematics is to study the
relationships that exist between variables. There are essentially two approaches
to doing this: visually and through formulas. Both of these methods will be explored in these notes.
Throughout these notes are various exercises and problems. These notes also
constitute an attempt to identify the essential elements of algebra and
trigonometry and to separate these elements from purely computational and formal
manipulations which can now be done by computers.
