To find the slope of the line tangent to the graph of (x^2xy + y^2 = 7), we differentiate the equation implicitly with respect to (x), then solve for (\frac{dy}{dx}).

Differentiating both sides with respect to (x) yields: [2x^2y + 2xy + x^2\frac{dy}{dx} + 2y\frac{dy}{dx} = 0]

Next, isolate (\frac{dy}{dx}): [\frac{dy}{dx}(x^2 + 2y) = -2x^2y - 2xy]

Divide both sides by (x^2 + 2y): [\frac{dy}{dx} = \frac{-2x^2y - 2xy}{x^2 + 2y}]

This expression represents the slope of the tangent line at any point on the curve.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
