Show that: tan2 x - 1/ tan x = tan x - cot xBad day of trig...
Shades...I think this is supposed to be :
[tan^2 x - 1]/ tan x = tan x - cot x working with the left side
tan^2x / tanx - 1/tanx =
tanx - cotx
Not too bad, huh???
My goodness... I think I need some extra coffee... that was too simple... Thanks a lot mate!
