To implicitly differentiate the equation (x y + 2x + 3x^2 = 4) with respect to (x), follow these steps:
- Differentiate each term of the equation with respect to (x).
- Apply the product rule when differentiating the term (xy).
- Solve for (\frac{dy}{dx}).
Here are the steps:
-
The differentiation of each term: [ \begin{align*} \frac{d}{dx}(xy) & = y + x\frac{dy}{dx} \ \frac{d}{dx}(2x) & = 2 \ \frac{d}{dx}(3x^2) & = 6x \end{align*} ]
-
Using the product rule for (\frac{d}{dx}(xy)): [ \frac{d}{dx}(xy) = y + x\frac{dy}{dx} ]
-
Putting it all together: [ y + x\frac{dy}{dx} + 2 + 6x = 0 ]
-
Rearrange to solve for (\frac{dy}{dx}): [ x\frac{dy}{dx} = -(y + 2 + 6x) \ \frac{dy}{dx} = -\frac{y + 2 + 6x}{x} ]
So, the implicit differentiation of (xy + 2x + 3x^2 = 4) with respect to (x) yields (-\frac{y + 2 + 6x}{x}).

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.
