December 13, 2002* 1. (20 pts.) Boyle’s Law states that when a gas is compressed at a con—
stant temperature, the pressure P and the volume V satisfy the equa" tion PV = C, Where C is a constant, Suppose that at a certain instant
the volume is 600 cm3, the pressure is 180 kPo, and the pressure is
increasing at a rate of 30 icPa/m'in. At what rate is the volume de creasing at this instant?
2. (10 pts.) Find the linearization L(:I:) of ﬁx) I oils at a z '3. 3. (10 pts.) Find the differential dy of y = coss: and evaluate rig for
