漏左題..... Given 0 < x < 90度. show that tan x - sin^2 x 4 ------------------- = --------------------------- - 1 tan x + sin^2 x 2 + sin 2x Hence, or otherwise, find the least value of tan x - sin^2 x ------------------- tan x + sin^2 x

.......!!!!!!!!!! 應該係咁!!!!!! Given 0 < x < 90度. show that tan x - sin^2 x 4 ------------------- = --------------------------- - 1 tan x + sin^2 x 2 + sin 2x Hence, or otherwise, find the least value of tan x - sin^2 x ------------------- tan x + sin^2 x
