Conditional Trigonometric Identities

This cheat sheet covers the high school math concept – Conditional Trigonometric Identities.

Conditional Trigonometric Identities

This concept is a part of Trigonometry. It covers a special case of trigonometric identities, in which a particular relation between the angles involved is known. This cheat sheet mainly focuses on trigonometric identities and inequalities involving three angles, whose sum is 180° (or π radians).

A basic knowledge of trigonometric ratios and related identities is a must for understanding these conditional trigonometric identities. A cheat sheet on Trigonometric Ratios and Identities is also available on this website.

All of these conditional identities are quite helpful in solving problems related to triangles and their properties, as these are directly applicable to any triangle. Cheat sheets on Properties and Solution of Triangles are also available on this website.

This one page PDF covers summarized theory and the most important formulas related to the concept. Keep it handy while you’re revising the concept, especially before an exam.

The topics included in this cheat sheet are:

  • Conditional Trigonometric Identities
  • Conditional Trigonometric Inequalities
