What are the parametric coordinates of x^2 + y^2 = 36 ?

Option: 1

x = 3 \cos \theta , y = 3 \sin \theta


Option: 2

x = 6 \cos \theta , y = 6 \sin \theta


Option: 3

x = 36 \cos \theta , y = 36 \sin \theta


Option: 4

None of these

As we have learned

Parametric form for x2 + y2 = r2 is

x= r\cos \Theta,   y= r\sin \Theta

 

 

 Since, in x^2 + y^2 = 36

r = 6 

Thus  x = 6\cos \theta , y = 6 \sin \theta
