sec x = 1/cos x 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...
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 ...
