Several important formulas, sometimesed logarithmic iden.ies or log laws, relate logarithms to one another Product, quotient, power and root. The logarithm of a product is the sum of the logarithms of the numbers being multiplied; the logarithm of the ratio .
Tan x y = tan x tan y / 1 tan x tan y . sin 2x = 2 sin x cos x. cos 2x = cos 2 x - sin 2 x = x - 1 = 1 - x . tan 2x = 2 tan x / 1 .
