A) \[\frac{x}{a}+\frac{y}{a}=a\cos \theta \]
B) \[x\text{ }cos\theta -y\text{ }sin\theta =a\text{ }cos2\theta \]
C) \[x\text{ }cos\theta +y\text{ }sin\theta =a\text{ }cos\text{ }2\theta \]
D) \[x\text{ }cos\theta +y\text{ }sin\theta -a\text{ }cos\text{ }2\theta =1\]
E) \[x\text{ }cos\theta -y\text{ }sin\theta +a\text{ }cos\text{ }2\theta =-1\]
