undefined equation.

Explanation:

sin (pi/2 - x) = cos x (supplementary arc)
#cot (pi/2 + x) = (cos (pi/2 + x))/(sin (pi/2 + x)) = sin x/(-cos x).#
The left side of the equation simplifies to:
#(cos x)(sin x/(-cos x)) = - sin x#,
Then, the equation reduces to:
-sin x = - sin x
The equation is undefined. It is insolvable.
