Trig Identities Trigonometric identities,trig identitiesor trig formulas for short, are equations that express the relationship between specified trigonometric functions. They remain true for all real number values of the assigned variables in them. The knowledge of trig identities is useful for solving ...

Trig identities are notoriously difficult to memorize: here’s how to learn them without losing your mind. Starting from the Pythagorean Theorem and similar triangles, we can find connections between sin, cos, tan and friends (read the article on trig). Can we go deeper? Maybe we can ...
The standard approach to finding antiderivatives of trigonometric expressions such as sin(ax) cos(bx) is to make use of certain trigonometric identities. The disadvantage of this technique is that it gives no insight into the problem, but relies on students using a memorized formula. This note ...
