Acos^2x+sin^2x=1.
Bcot x= cosx/sinx.
Ccos x= 1/sec x.
Dsin x= 1/csc x. .

2.What basic trigonometric identity would you use to verify that sin^2x+cos^2x/cosx= sec x?.

Asin x=1/csc x.
B1+cot^2x=csc^2x.

1 ) cot x sin x = cos x
(cos x / sin x) sin x = cos x 
cos x = cos x
Answer: B ) cot x = cos x / sin x
2 ) ( sin² x + cos² x ) / cos x = sec x
1/cos x = sec x
sec x = sec x
Answer: C ) cos² x + sin² x = 1
