You can't verify it since it is not an identity.
Explanation:
You can't since this is not true.
To prove that this is not an identity, find one
For example, you can take
As you know,
#sin(pi/3) / cos(pi/3) + cos(pi/3)/sin(pi/3) = (sqrt(3)/2)/(1/2) + (1/2)/(sqrt(3)/2) = sqrt(3)/1 + 1 / sqrt(3) = 4 / sqrt(3) != 1 #
Thus, this equation is not an identity.

The given equation is not true
and therefore can not be verified.
