Hi, I am trying to find x in
(tanx+)(cosx-1)
I FOILed:
sin+cos-tan-1=0
sin+cos-(sin/cos)-1=0
now I am stuck.
please help, any help will be greatly appreciated.

You don't have to foil my friend...
$\displaystyle (\tan{x}+1)(\cos{x}-1)=0$
Thhis statement implies that
$\displaystyle \tan{x}=-1$
or
$\displaystyle \cos{x}=1$
.
