The parametric surface shown in figure 1 hasgrid curves which can be shown to be circles when is constant
x=(2+sin(v))cos(u)
y=(2+sin(v))sin(u)
z=u+cos(v)
find the center and radius of the circle at u=pi
please help me

1. Plug in . You'll get the vector:
2. From
...... and
you'll get by squaring:
3. This is the equation of a circle in the x-z-plane with and r = 1
