**Using Numerical Values**

**19.** Suppose that \( u \) and \( v \) are functions of \( x \) that are differentiable at \( x = 0 \) and that:

\[
u(0) = 5, \quad u'(0) = 3
\]
\[
v(0) = -1, \quad v'(0) = 2
\]

Find the values of the following derivatives at \( x = 0 \).

(a) \(\frac{d}{dx}(uv)\)

(b) \(\frac{d}{dx}\left(\frac{u}{v}\right)\)

(c) \(\frac{d}{dx}\left(\frac{v}{u}\right)\)

(d) \(\frac{d}{dx}(7v - 2u)\)

**20.** Suppose that \( u \) and \( v \) are differentiable functions of \( x \) and that:

\[
u(1) = 2, \quad u'(1) = 0
\]
\[
v(1) = 5, \quad v'(1) = -1
\]

Find the values of the following derivatives at \( x = 1 \).

(a) \(\frac{d}{dx}(uv)\)

(b) \(\frac{d}{dx}\left(\frac{u}{v}\right)\)

(c) \(\frac{d}{dx}\left(\frac{v}{u}\right)\)

(d) \(\frac{d}{dx}(7v - 2u)\)
