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 ...

These hyperbolic identities are very useful when calculating hyperbolic integrals.Hyperbolic Sine Recall that the trig functions sin(x) and cos(x) relate the ratio of the legs in a right triangle to an angle in a circle. If a line is drawn from the center of a circle to its circumference...
Tan (x+π) = tan x Cos (x+π) = cos x Sin (x+2π) = sin x The other category of trigonometry formulas includes sum/difference identities, formulas with cofunction identities, product identities, sum to product identities, half angle identities and double angle identities. You can learn...
