Unformatted text preview: , = 0. tan −x = − tan x. tan • 1 • Formula. d dx tan x = • Formula. d dx tan x = 1 + 2 . 2 1 −x = Alternatively: cos x tan x π 2 . 1 . tan x Addition Formula for tan x. Knowing sin x+y = sin x cos y + cos x sin y cos x+y = cos x cos y − sin x sin y , sin x cos y + cos x sin y cos x cos y − sin x sin y tan x + tan y tan x and tan y you may find tan x+y = , that is, tan x+y . = 1− Double Angle formula. • 2 (♣) • tan 2x tan x = 2 1− . tan x Understand the following: 1 . 5 Let α1 be a real number such that tan α1 = Formula (♣...
