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...
Before we can move to the fun stuff of real life applications of trigonometry, it is important to take a closer look at the various functions of trigonometry. Trigonometric Identities These can be confusing to understand and memorize however these for the basis of all trigonometric values and der...

The identities sin(180° −x) = sin(x) and cos(180° −x) = −cos(x) let you reduce the range further to between 0 and 90°. Finally, the identities cos(x) = sin(90° −x) and sin(x) = cos(90° −x) can reduce the range to 0° to 45°. Interpolation You can...
These formulas are especially important in higher-level math courses, calculus in particular. Also called the power-reducing formulas, three identities are included and are easily derived from the double-angle formulas. We can use two of the three double-angle formulas for cosine to derive t...
