Here, we show you a step-by-step solved example of implicit differentiation. This solution was automatically generated by our smart calculator:

Apply implicit differentiation by taking the derivative of both sides of the equation with respect to the differentiation variable
d d x ( x 2 + y 2 ) = d d x ( 16 ) \frac{d}{dx}\left(x^2+y^2\right)=\frac{d}{dx}\left(16\right) d x d β ( x 2 + y 2 ) = d x d β ( 16 )

The derivative of a sum of two or more functions is the sum of the derivatives of each function

We need to isolate the dependent variable y y y 2 x 2x 2 x
2 y β
y β² = β 2 x 2y\cdot y^{\prime}=-2x 2 y β
y β² = β 2 x

Divide both sides of the equation by y y y
y β² = β x y y^{\prime}=\frac{-x}{y} y β² = y β x β
