Cot^2x - cot^2x cos^2x
= cot^2x - {(cot^2x)(cos^2x)}
= cot^2x { 1 - cos^2x }
= cot^2x { sin^2x }
= (cos^2x/sin^2x) { sin^2x }
= cos^2x

Answer:
E (3,-1) D (-2, -2) G (-1, 3) F (3, 2)
Step-by-step explanation:
90 degrees = (y, -x)
that means you take the ordered pair you want to rotate and plug the x and y into the new spots.
for example, point E is at (1,3) so the point rotated 90 degrees is (3,-1)
I think its 12.
I could be wrong. Let me know.
