Question 1

What kind of curve  is  r(t) = (sin t) i + (sin t) j + 2(cos t) k?
◦ a circular helix
◦ a parabola
◦ a circle
◦ an ellipse (but not a circle)
◦ an oval plane curve that is, however, not an ellipse

Question 2

Describe the curve r(t) = (sin t) i + (cos t) j + k.
◦ the circle (of radius 1) in which the plane  z =  intersects the sphere  x2 + y2 + z2 = 4
◦ the circle (of radius ) in which the plane  z = 1  intersects the sphere  x2 + y2 + z2 = 3
◦ a helix wound around the cylinder  x2 + y2 =  3
◦ the circle (of radius ) in which the plane  z =  intersects the cylinder  x2 + y2 = 1
◦ a helix wound around the cylinder  x2 + y2 = 1
