cot x = 1/tanx
1/tan x - tanx - cosx +sinx =0
1-tan^2x/tanx......
sec^2 x /tanx.....
1/sinx cosx +sinx - cosx=
sinx + 1/sinx cosx - cosx = 0
sinx + 2/sin 2x - cos x = 0
On Solvin Further........u Get x = pie/4
Please Rate Me iF u found my solution adequate

Forget The Earlier Method.......I Found An Excellent One
S = Sin x
C = cos x
c/s - s/c - c + s = 0
LCM
sc - s^2 - s c^2 + s^2 c = 0
c - s - c^2 + sc = 0
c - c^2 = s - sc
c (1 - c) = s ( 1 - c)
c = s
tan x = 1
x = pi/4
hain na kamal ?? LOL Just Kiddin.....Now Please Gimme A Rate Or Two :)

hi nunoxic
wont the lcm be = c^2 - s^2 - s c^2 + s^2 c = 0
?
