試題 :
1. A martini glass in the shape of a right-circular cone of height h \ O /
and semivertical angle α is filled with liquid. Slowly a ball is \ /
lowered into the glass, displacing liquid and causing it to overflow. ||
Find the radius R of the ball that causes the greatest volume of liquid to
overflow out of the glass. (2/10)
2. Initially a tank contains 1,000 L of brine with 50 kg of dissolved salt.
Brine containing 10 g of salt per litre is flowing into the tank at a
constant rate of 12 L/min. If the contents of the tank are kept throughly
mixed at all times, and if the solution flows out at 10 L/min, how much
salt remains in the tank at the end of 40 min? (2/10)
3. A 45°notch is cut one quarter way (10 cm) into a cylindrical log having
radius 20 cm. One plane face of the notch is perpendicular to the axis of
the log. What volume of wood was removed from the log by cutting the
notch? (2/10)
4. Find the area bounded the loop of the parametric curve x = t^3 - t,
y = |t^3|, and its asymptotes. Sketch the curve. (2/10)
95 nπ π
5. Riemann sum Σ (sin -- ) -- = ? (2/10)
n=1 95 95
