hey, that's just cot^2(x)!
cos^2 + cos^2 cos^2 ----------- is what I see so far sin^2
=cos^2(x)(1+cos^2(x)/sin^2(x)) =cos^2(x)((sin^2(x)+cos^2(x))/sin^2(x)) =cos^2(x)/sin^2(x) =cot^2(x)
work of art i say
or factor out a cos^2 lol

cos^2(1+cot^2) cos^2(csc^2) cos^2 ----- = 1 ...... cos^2
let me check my 1+cot^2
sin^2 + cos^2 = 1 ------------ ---- sin^2 sin^2 sin^2 1 + cot^2 = csc^2.... my bad lol
cos^2 ----- = cot^2 smarty was right :) sin^2
yours more elegant tho

csc=1/sin^2
i did it on the fly
i did it with one synapse tied behind my right prefrontal lobe ;)
