Answer 1

A.cos^2 theta/(1+sintheta)^2 B.cos^2theta/(1-sintheta)^2. C.(1+sintheta)^2/cos^2theta D.(1-sintheta)^2/cos^2theta

Answer 2

Multiple both numerator and denominator by (1+sin ) what do you get?

Answer 3

1+sin theta^2 over cos^2 theta

Answer 4

It can also have more than one answer. Is that the only answer?

Answer 5

if you multiple by (1-sin) , you get???

(1-sin theta)^2/cos^2 theta?

Answer 7

nope for the last answer

Answer 8

Cos^theta/(1-sintheta)^2?

Answer 9

yup
