Find the surface area of this ellipsoid.
(b) If the ellipse in part (a) is rotated about its minor exis (the y-axis), the resulting ellipsoid is called an oblate spheroid.

What do your answers to part (a) tell you about the flow of blood in this artery?
Make a table of values of

Find the net change in the velocity 
is the speed of light in one medium and 
is its speed in another medium, then according to Snell's Law,
is the angle of incidence and 
, is the angle of refraction (see the figure). The number 
is called the index of refraction. The index of refraction for several sub-stances is given in the table. If a ray of light passes through the surface of a lake at an angle of incidence of 
what is the angle of refraction?
