(\partial)/(\partial s)(r-s)

\frac{\partial}{\partial s} (r - s)

- 1

Solution steps

\frac{\partial}{\partial s} (r - s)

Treat

r

as a constant

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{\partial}{\partial s} (r) - \frac{\partial}{\partial s} (s)

\frac{\partial}{\partial s} (r) = 0

\frac{\partial}{\partial s} (s) = 1

= 0 - 1

Simplify

= - 1
