Basic Trigonometric Identities All trigonometric identities are derived using the six basic trigonometric ratios. These are sine (sin), cosine (cos), tangent (tan), cosecant (csc), secant (sec), and cotangent (cot). Fig 1: Trig Ratios Chart FIg 1 displays a chart that can be used to ...
Tags identities Trig Trig identities In summary, the conversation discusses the trigonometric identities for cos(90+theta) and sin(90+theta) and clarifies that cos is negative in the second quadrant while sin is positive. The conversation also mentions using the unit circle and sums/differences or...
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 ...
