Chapter 14.3, Problem 3E

(a)

To determine

To estimate: The values of $f_T\left(-15,30\right)$ and $f_v\left(-15,30\right)$ from Table 1 and interpret these values.

(b)

To determine

To explain: The signs of $\frac{\partial W}{\partial T}$ and $\frac{\partial W}{\partial v}$ using Table 1.

(c)

To determine

To find: The limit, $\underset{v\to \infty }{\lim }\frac{\partial W}{\partial v}$ of the function $W=f\left(T,v\right)$.
