tan x = 1/cot x cot x = 1/tan x What is sin 2x identity? sin 2x = 2sin(x)cos(x) The sin 2x identity is a double angle identity. It can be used to derive other identities. Trig Identities Trigonometric identities,trig identitiesor trig formulas for short, are equations that expres...
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 ...

Related to Hyperbolic trig identities:Hyperbolic trig functions hyperbolic function n. Any of a set of six functions related, for a real or complex variablex,to the hyperbola in a manner analogous to the relationship of the trigonometric functions to a circle, including: ...
Many trig classes have you memorize these identities so you can be quizzed later (argh). You don’t need to memorize them, you can work out the formula in about a minute. Save your precious brain space for something else. 2. We can now “factor” trig functions into simper parts. We...
