You can also get the "Reciprocal Identities", by going "through the 1"Here you can see that sin(x) = 1 / csc(x)Here is the full set:sin(x) = 1 / csc(x) cos(x) = 1 / sec(x) cot(x) = 1 / tan(x) csc(x) = 1 / sin(x) sec(x) = 1 / cos(x) tan(x) = 1 ...

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 Trigonometric Identities we introduced the(Sines, Cosines and Tangents). We begin by reminding ourselves of the 2X + Cos2X = 1 In addition, there are relations called: Sin 2X = 2 Sin X Cos X Cos 2X = Cos2X - Sin2X Because SinX + CosX = 1, this last relation can also be ...
