No solution exist.

Explanation:

Solve for #x#

# {1 - cos ^2 x}/tan x= sin x cot x#

# sin^2 x = sin x cot x tan x = sin x#

#sin x( sin x - 1) = 0#

#sin x = 0 or sin x = 1#

We can rule out #sin x = 0# for an undefined cotangent and #sin x=1# meaning #cos x = 0# for an undefined tangent. So no solutions.
