Question

how to convert polar equations to a rectangular equation, r=2/2-2cos(theta)

Answer 1

Keep in mind that \[r^2=x^2+y^2\] and \[x=rcos(theta)\]

Answer 2

does this apply to other functions too like sec?

Answer 3

example:
\[r= 2 \sec(\theta) \\ r=2 \frac{1}{\cos(\theta)} \\ r \cos(\theta)=2(1) \\ r \cos(\theta) =2 \\ x =2 \]
yep it applies!

Answer 4

thank you!

Answer 5

are you able to convert yours to rectangular form?
