Dec 21, 2005 ... arcsech(x) = ln((1 + sqrt(1 - x^2)) / x). cot x = 1 / tan x. coth x = cosh x / sinh x. csc x = 1 / sin x. csch x = 1 / sinh x. log(x,y) = log10( ... The reciprocal identities are: csc(x) = 1/sin(x), sec(x) = 1/cos(x), and cot(x) = 1/tan(x). We have cot 3x = cot (2x+x). ⇒(cot 2x cot x)-1cot 2x + cot x. ∴ cot 3x (cot 2x+ cot x)= (cot 2x. cot x)-1. ⇒ cot 3x . cot 2x+ cot 3x . cot x = (cot 2x . cot x) ... ω11 = ω0 * cot(x1), ω12 = ω0 * cot(x2), ω21 = ω0 * tan(x1) and ω22 = ω0 ...
