SUMMARY
The discussion focuses on calculating the dot product of the vector expression i dot 1/√2( i + j). The correct approach involves recognizing that the dot product of two vectors is the sum of the products of their corresponding components. Specifically, for the vectors (1,0) and (1/√2, 1/√2), the calculation confirms that i dot i equals 1 and i dot j equals 0, leading to a final result of 1/√2.
