Find the second derivative with respect to y

\frac{d ^{2} y}{d x ^{2}} = \frac{6 y}{x ^{2}}

Calculate

(x^{2}) 2 (y 1) 2 = 4

Simplify the expression

4 x^{2} y = 4

Take the derivative of both sides

\frac{d}{d x} (4 x^{2} y) = \frac{d}{d x} (4)

Calculate the derivative

More Steps

8 x y + 4 x^{2} \frac{d y}{d x} = \frac{d}{d x} (4)

Calculate the derivative

8 x y + 4 x^{2} \frac{d y}{d x} = 0

Move the expression to the right-hand side and change its sign

4 x^{2} \frac{d y}{d x} = 0 - 8 x y

Removing 0 doesn't change the value,so remove it from the expression

4 x^{2} \frac{d y}{d x} = - 8 x y

Divide both sides

\frac{4 x ^{2} \frac{d y}{d x}}{4 x ^{2}} = \frac{- 8 x y}{4 x ^{2}}

Divide the numbers

\frac{d y}{d x} = \frac{- 8 x y}{4 x ^{2}}

Divide the numbers

More Steps

\frac{d y}{d x} = - \frac{2 y}{x}

Take the derivative of both sides

\frac{d}{d x} (\frac{d y}{d x}) = \frac{d}{d x} (- \frac{2 y}{x})

Calculate the derivative

\frac{d ^{2} y}{d x ^{2}} = \frac{d}{d x} (- \frac{2 y}{x})

Use differentiation rules

\frac{d ^{2} y}{d x ^{2}} = - \frac{\frac{d}{d x} ( 2 y ) \times x - 2 y \times \frac{d}{d x} ( x )}{x ^{2}}

Calculate the derivative

More Steps

\frac{d ^{2} y}{d x ^{2}} = - \frac{2 \frac{d y}{d x} \times x - 2 y \times \frac{d}{d x} ( x )}{x ^{2}}

Use \frac{d}{d x} x^{n} = n x^{n - 1} to find derivative

\frac{d ^{2} y}{d x ^{2}} = - \frac{2 \frac{d y}{d x} \times x - 2 y \times 1}{x ^{2}}

Use the commutative property to reorder the terms

\frac{d ^{2} y}{d x ^{2}} = - \frac{2 x \frac{d y}{d x} - 2 y \times 1}{x ^{2}}

Any expression multiplied by 1 remains the same

\frac{d ^{2} y}{d x ^{2}} = - \frac{2 x \frac{d y}{d x} - 2 y}{x ^{2}}

Use equation \frac{d y}{d x} = - \frac{2 y}{x} to substitute

\frac{d ^{2} y}{d x ^{2}} = - \frac{2 x ( - \frac{2 y}{x} ) - 2 y}{x ^{2}}

Solution
