The Deep Dive
To find \( \frac{dy}{dx} \) using implicit differentiation for the equation \( 3xy^2 = x - 10 \), we start by differentiating both sides with respect to \( x \): 1. Differentiate the left side: \[ \frac{d}{dx}(3xy^2) = 3\left( x\frac{d}{dx}(y^2) + y^2\frac{d}{dx}(x) \right) = 3\left( x(2y\frac{dy}{dx}) + y^2 \right) = 3y^2 + 6xy\frac{dy}{dx} \] 2. Differentiate the right side: \[ \frac{d}{dx}(x - 10) = 1 \] Now, we set the derivatives equal: \[ 3y^2 + 6xy\frac{dy}{dx} = 1 \] Next, isolate \( \frac{dy}{dx} \): \[ 6xy\frac{dy}{dx} = 1 - 3y^2 \] \[ \frac{dy}{dx} = \frac{1 - 3y^2}{6xy} \] So, the derivative \( \frac{dy}{dx} \) is: \[ \frac{dy}{dx} = \frac{1 - 3y^2}{6xy} \]
