Question

Rewrite in polar form: x=12. I have r=12 sec theta

Answer 1

Answer:

C. r=12Secθ

Step-by-step explanation:

Answer 2

To solve this problem you must apply the proccedure shown below:
 1. You have to rewrite x=12 in polar form. Then, you have:
 12=rCosθ
 2. Then, you must solve for r, as following:
 r=12/Cosθ
 3. You have that 1/Cosθ=Secθ, therefore:
 r=12(1/Cosθ)
 r=12Secθ
 Therefore, as you can see, the answer is: r=12Secθ
