Find the second derivative with respect to x

Find the second derivative with respect to y

\frac{d ^{2} y}{d x ^{2}} = - \frac{3}{4 y ^{7}}

Calculate

2 x - y^{4} = 0

Take the derivative of both sides

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

Calculate the derivative

More Steps

2 - 4 y^{3} \frac{d y}{d x} = \frac{d}{d x} (0)

Calculate the derivative

2 - 4 y^{3} \frac{d y}{d x} = 0

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

- 4 y^{3} \frac{d y}{d x} = 0 - 2

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

- 4 y^{3} \frac{d y}{d x} = - 2

Divide both sides

\frac{- 4 y ^{3} \frac{d y}{d x}}{- 4 y ^{3}} = \frac{- 2}{- 4 y ^{3}}

Divide the numbers

\frac{d y}{d x} = \frac{- 2}{- 4 y ^{3}}

Cancel out the common factor - 2

\frac{d y}{d x} = \frac{1}{2 y ^{3}}

Take the derivative of both sides

\frac{d}{d x} (\frac{d y}{d x}) = \frac{d}{d x} (\frac{1}{2 y ^{3}})

Calculate the derivative

\frac{d ^{2} y}{d x ^{2}} = \frac{d}{d x} (\frac{1}{2 y ^{3}})

Use differentiation rules

\frac{d ^{2} y}{d x ^{2}} = \frac{1}{2} \times \frac{d}{d x} (\frac{1}{y ^{3}})

Rewrite the expression in exponential form

\frac{d ^{2} y}{d x ^{2}} = \frac{1}{2} \times \frac{d}{d x} (y^{- 3})

Calculate the derivative

More Steps

\frac{d ^{2} y}{d x ^{2}} = \frac{1}{2} (- 3 y^{- 4} \frac{d y}{d x})

Rewrite the expression

\frac{d ^{2} y}{d x ^{2}} = \frac{1}{2} (- \frac{3 \frac{d y}{d x}}{y ^{4}})

Calculate

\frac{d ^{2} y}{d x ^{2}} = - \frac{3 \frac{d y}{d x}}{2 y ^{4}}

Use equation \frac{d y}{d x} = \frac{1}{2 y ^{3}} to substitute

\frac{d ^{2} y}{d x ^{2}} = - \frac{3 \times \frac{1}{2 y ^{3}}}{2 y ^{4}}
