Tan = sin / cos./ / /
Tan cos = (sin/cos) cos = sin = 0 / / / x = any multiple of 180 degrees.

To solve tan x cos x = 0 , set each factor to zero: tan x = 0 gives x = kπ , while cos x = 0 gives x = 2 π ​ + kπ , with k ∈ Z . Thus, the complete solution set is formed by both equations' solutions. These represent all x-values where either tangent or cosine is zero.
