Question
Find the limit, if it exists, or type dne if it does not exist.
\lim_{(x,y) \to (-35,5)} xy \cos(x + 7y) =
Solution
To find the limit , we can follow these steps:
1. Break Down the Problem
We need to evaluate the limit of the function as approaches .
2. Relevant Concepts
We generally apply the limit as follows:
- Evaluate
- Handle the components separately as approaches the specified point.
3. Analysis and Detail
Evaluate the individual components at the limit point :
-
Calculate and :
-
