### Problem Statement

Given the function:

\[ h(x, y, z) = x \sin(x + 2y + 3z) \]

Let \( P \) be the point \( (\pi, \pi, 0) \).

1. **Find \( k \in \mathbb{R} \) such that \( P \) lies on the level set**  
   \[ \Lambda : h(x, y, z) = k \]

2. **Find a formula for the plane tangent to \( \Lambda \) at \( P \).**

Expert Solution
Step 1: Writing down the given information

Given the function h open parentheses x comma y comma z close parentheses equals x sin open parentheses x plus 2 y plus 3 z close parentheses and the point P open parentheses pi comma pi comma 0 close parentheses.

Consider the level set capital lambda colon h open parentheses x comma y comma z close parentheses equals k.

We need to find kR such that h(π,π,0)=k.
