**Reiny**, Sunday, December 7, 2008 at 5:27pmI too am slightly frustrated, since I can't tell which order of operation to follow with your placement of brackets

is it sinx/cosx - [1/(sinx/cosx)] - 1 ??

if so, you have

tanx - 1/cotx - 1

= tanx - tanx - 1

= -1

(tan^2 x - tan x) / (1 - tan x)

tan x (tan x - 1)/(1 - tan x)

-tan x
