$$cosec^26a-cot^26a\\\\ =\frac{1}{sin^26a}-\frac{cos^26a}{sin^26a}\\\\ =\frac{1-cos^26a}{sin^26a}\\\\ =\frac{sin^26a}{sin^26a}\\\\ =1$$
I'm confused.
What is the question?
I think they might mean this:
csc^2 (6a) - cot^2 (6a)
If so, using a trig identity, the answer is (wait for it!!)
1 = ONE = "WUN" = "UNO"
