This encyclopedia contains trigonometric identity proofs for some three hundred identities. The book is presented in the form of mathematical games for the reader's enjoyment and includes a concordance of trigonometric identities, enabling easy reference.Trig or Treat is a must-have for:* every student of trigonometry, to find the proofs for trigonometric identities that may be set in class or in exams;* every teacher of trigonometry, to have easy access to trigonometric identities of different levels of difficulty, to set assignments for different levels of students;* every library, to provide a ready resource for students* every aficionado of Sudoku, crossword puzzles, jigsaw puzzles, Tetris, and other games, who love an intellectual challenge.

This is a mathematics book written specifically for the enjoyment of non-mathematicians and those who "hated math in school." The book is organized into two sections: (I) Beauty for the Eye (shallow water for the non-swimmer); and (II) A Feast for the Mind (slowly getting deeper for the more adventurous). The author covers beautiful infinite series beginning with those that a young child can understand to one that even Isaac Newton, Gottfried Liebniz and the famous Bernoulli brothers could not sum.
