Find the derivative with respect to x

Find the derivative with respect to y

Show Solution

Find the second derivative with respect to x

Find the second derivative with respect to y

\frac{d ^{2} y}{d x ^{2}} = \frac{7 y}{36 x ^{2}}

Calculate

x y^{5} y = - 2

Simplify the expression

x y^{6} = - 2

Take the derivative of both sides

\frac{d}{d x} (x y^{6}) = \frac{d}{d x} (- 2)

Calculate the derivative

More Steps

y^{6} + 6 x y^{5} \frac{d y}{d x} = \frac{d}{d x} (- 2)

Calculate the derivative

y^{6} + 6 x y^{5} \frac{d y}{d x} = 0

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

6 x y^{5} \frac{d y}{d x} = 0 - y^{6}

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

6 x y^{5} \frac{d y}{d x} = - y^{6}

Divide both sides

\frac{6 x y ^{5} \frac{d y}{d x}}{6 x y ^{5}} = \frac{- y ^{6}}{6 x y ^{5}}

Divide the numbers

\frac{d y}{d x} = \frac{- y ^{6}}{6 x y ^{5}}

Divide the numbers

More Steps

\frac{d y}{d x} = - \frac{y}{6 x}

Take the derivative of both sides

\frac{d}{d x} (\frac{d y}{d x}) = \frac{d}{d x} (- \frac{y}{6 x})

Calculate the derivative

\frac{d ^{2} y}{d x ^{2}} = \frac{d}{d x} (- \frac{y}{6 x})

Use differentiation rules

\frac{d ^{2} y}{d x ^{2}} = - \frac{\frac{d}{d x} ( y ) \times 6 x - y \times \frac{d}{d x} ( 6 x )}{( 6 x ) ^{2}}

Calculate the derivative

More Steps

\frac{d ^{2} y}{d x ^{2}} = - \frac{\frac{d y}{d x} \times 6 x - y \times \frac{d}{d x} ( 6 x )}{( 6 x ) ^{2}}

Calculate the derivative

More Steps

\frac{d ^{2} y}{d x ^{2}} = - \frac{\frac{d y}{d x} \times 6 x - y \times 6}{( 6 x ) ^{2}}

Use the commutative property to reorder the terms

\frac{d ^{2} y}{d x ^{2}} = - \frac{6 \frac{d y}{d x} \times x - y \times 6}{( 6 x ) ^{2}}

Use the commutative property to reorder the terms

\frac{d ^{2} y}{d x ^{2}} = - \frac{6 \frac{d y}{d x} \times x - 6 y}{( 6 x ) ^{2}}

Use the commutative property to reorder the terms

\frac{d ^{2} y}{d x ^{2}} = - \frac{6 x \frac{d y}{d x} - 6 y}{( 6 x ) ^{2}}

Calculate

More Steps

\frac{d ^{2} y}{d x ^{2}} = - \frac{6 x \frac{d y}{d x} - 6 y}{36 x ^{2}}

Calculate

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

Use equation \frac{d y}{d x} = - \frac{y}{6 x} to substitute

\frac{d ^{2} y}{d x ^{2}} = - \frac{x ( - \frac{y}{6 x} ) - y}{6 x ^{2}}

Solution
