Question

the regular coordinates of a point are given find the polar coordinates of each point, (4,0)

Answer 1

(x,y)=(rcos(theta), rsin(theta))
rcos(theta)=x=4
rsin(theta)=y=0
(4,0) is in the first quadrant
so rsin(theta)=0 => sin(theta)=0 => theta=0

so if rcos(theta)=4 and theta=0, then rcos(0)=r(1)=r=4

Answer 2

polar coordinate in this case is the same as the rectangular cooridate
(r,theta)=(4,0)

Answer 3

yeah for some reason i got hte answer was (4,0) but i thought that it was wrong

Answer 4

because it was the same? lol

Answer 5

yeah haha
