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