x + 1 = tan x = ↔ tan x = Jika digambarkan dalam segitiga : Sehingga sin x = x =

begin mathsize 14px style tan squared end style x + 1 = undefined

tan x = begin mathsize 14px style square root of a squared minus 1 end root end style ↔ tan x = $begin mathsize 14px style fraction numerator square root of a squared minus 1 end root over denominator 1 end fraction end style$

Jika digambarkan dalam segitiga :

begin mathsize 14px style square root of a squared minus 1 end root end style
