The solution will be posted in a sequential hint based format. You have to verify the steps of hints.
Step 1:
Solution set of sin(\(\frac{x+y}{2}\)) = 0 is {\({x + y = 2n\pi : n \in \mathbb{N}}\)}
- A set of parallel straight lines.
Step 2:
Solution set of |x| + |y| = 1 has the picture of a diamond as follows:
Step 3:
Combine the two pictures, please!
Step 4:
