![**Problem Statement:**
Find \( \frac{\partial w}{\partial r} \) when \( r = 5 \) and \( s = -5 \) given the equations:
\[
w = (x + y + z)^2
\]
where
\[
x = r - s, \quad y = \cos(r + s), \quad z = \sin(r + s).
\]
---
**Solution Step:**
Evaluate \( \frac{\partial w}{\partial r} \) at \( r = 5 \), \( s = -5 \).
---
**Expression to Simplify:**
\[
\left. \frac{\partial w}{\partial r} \right|_{r=5,\, s=-5} = \boxed{}
\]
