the answer is c
since (1-cos^2(tada))=sin^2(tada)
and sin^2(tada)/cos^2(tada)=tan^2(tada)

The answer is 3, tan^2(tada).
1-cos^2 = sin^2, so your expression is equal to
sin^2/cos^2
sin/cos = tan, so sin^2/cos^2 = tan^2.

1 - cos^2x = sin^2 x
sin x / cos x = tan x
so the ans is 3.

the correct answer is no.3, tan^2x. this is because the numerator of the fraction, (1-cos^2x) is equal to sin^2x, based on the pythagorean identities in trigonometry.
the fraction thus becomes sin^2x/cos^2x or tan^2x.
fyi please.
