sec x-csc x=(1/cos x)- (1/sin x)=(sin x-cos x)/cos x * sin x--numerator
sec x + csc x=(sin x + cos x)/cos x* sin x--denominator.
(sin x - cos x)/cos x * sin x divided by (sin x + cos x)/cos x* sin x
Now cancel just the sin x in both denominators.
(sin x- cos x)/cos x divided by (sin x+ cos x)/cos x
This is tan x-1/tan x +1
