I'm having trouble with this question, can somebody please help me with it! I'll thanks/like your comment if help me =)

![Question][1]

I know that for a ellipse the parametric is x=a sin t , b= b cos t t:0 to 2pi (?)

for part a) I drew up the graph but not sure if it's right. the circle have 1 radius and for the ellipse I able to find the x= 2

(x-1)^2 =9

sqrt(x-1)^2=sqrt9

x-1=3

x=4

for y=2sqrt2

y^2=8

sqrty=sqrt8

y=sqrt4 sqrt 2

y= 2sqrt2 or 2.8

So the region should be the circle? since the ellipse like cover the whole circle?

Thank you very much for helping!

Cheers.
