Math Problem Statement
Solution
The problem asks to find the vector using the properties of cross products rather than using determinants.
Let's break it down:
-
Step 1: Compute
From the standard basis vectors in 3D, we know that: So, . -
Step 2: Compute
Now, we need to compute . The cross product of any vector with itself is always the zero vector:
Therefore, the result of is the zero vector:
