SUMMARY
The discussion focuses on the differentiation of the function \( s = \sqrt{6x^2 + 2y^2} \) with respect to \( t \) while treating \( y \) as a constant. The derivative is expressed as \( \frac{ds}{dt} = \frac{6x \frac{dx}{dt}}{\sqrt{6x^2 + 2y^2}} \) since \( \frac{dy}{dt} = 0 \). Participants clarify that the negative sign in the original expression arises from a misunderstanding of the terms involved in the differentiation process. The denominator simplifies to \( \sqrt{6x^2 + 2y^2} \), confirming that the \( 2y^2 \) term does not contribute when \( y \) is constant.
