Find a Parameterization for the Circle of Radius 4 in the Xz-Plane

Question 13

Multiple Choice

Find a parameterization for the circle of radius 4 in the xz-plane, centered at the point (3, 0, -5) .Select all that apply.


A) x=3+4cost,y=0,z=5+4sintx = 3 + 4 \cos t , y = 0 , z = 5 + 4 \sin t
B) r=(3i5k) +4(costi+sintk) \vec { r } = ( 3 \vec { i } - 5 \vec { k } ) + 4 ( \cos t \vec { i } + \sin t \vec { k } )
C) x=34sint,y=0,z=5+4costx = 3 - 4 \sin t , y = 0 , z = - 5 + 4 \cos t
D) r=(5i3k) +4(costi+sintk) \vec { r } = ( 5 \vec { i } - 3 \vec { k } ) + 4 ( \cos t \vec { i } + \sin t \vec { k } )
E) x=3+4cost,y=0,z=5+4sintx = 3 + 4 \cos t , y = 0 , z = - 5 + 4 \sin t
