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

Calculate

24 x 19 y = 1

Simplify the expression

456 x y = 1

Take the derivative of both sides

\frac{d}{d x} (456 x y) = \frac{d}{d x} (1)

Calculate the derivative

More Steps

456 y + 456 x \frac{d y}{d x} = \frac{d}{d x} (1)

Calculate the derivative

456 y + 456 x \frac{d y}{d x} = 0

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

456 x \frac{d y}{d x} = 0 - 456 y

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

456 x \frac{d y}{d x} = - 456 y

Divide both sides

\frac{456 x \frac{d y}{d x}}{456 x} = \frac{- 456 y}{456 x}

Divide the numbers

\frac{d y}{d x} = \frac{- 456 y}{456 x}

Divide the numbers

More Steps

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

Take the derivative of both sides

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

Calculate the derivative

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

Use differentiation rules

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

Calculate the derivative

More Steps

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

Use the commutative property to reorder the terms

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

Any expression multiplied by 1 remains the same

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

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

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

Solution

Conic

\frac{( x ^{'} ) ^{2}}{\frac{1}{228}} - \frac{( y ^{'} ) ^{2}}{\frac{1}{228}} = 1

Evaluate

24 x \times 19 y = 1

Move the expression to the left side

24 x \times 19 y - 1 = 0

Calculate

456 x y - 1 = 0

The coefficients A,B and C of the general equation are A= 0,B= 456 and C= 0

A = 0 B = 456 C = 0

To find the angle of rotation θ,substitute the values of A,B and C into the formula cot (2 θ) = \frac{A - C}{B}

cot (2 θ) = \frac{0 - 0}{456}

Calculate

cot (2 θ) = 0

Using the unit circle,find the smallest positive angle for which the cotangent is 0

2 θ = \frac{π}{2}

Calculate

θ = \frac{π}{4}

To rotate the axes,use the equation of rotation and substitute \frac{π}{4} for θ

x = x^{'} cos (\frac{π}{4}) - y^{'} sin (\frac{π}{4}) y = x^{'} sin (\frac{π}{4}) + y^{'} cos (\frac{π}{4})

Calculate

x = x^{'} \times \frac{2}{2} - y^{'} sin (\frac{π}{4}) y = x^{'} sin (\frac{π}{4}) + y^{'} cos (\frac{π}{4})

Calculate

x = x^{'} \times \frac{2}{2} - y^{'} \times \frac{2}{2} y = x^{'} sin (\frac{π}{4}) + y^{'} cos (\frac{π}{4})

Calculate

x = x^{'} \times \frac{2}{2} - y^{'} \times \frac{2}{2} y = x^{'} \times \frac{2}{2} + y^{'} cos (\frac{π}{4})

Calculate

x = x^{'} \times \frac{2}{2} - y^{'} \times \frac{2}{2} y = x^{'} \times \frac{2}{2} + y^{'} \times \frac{2}{2}

Substitute x and y into the original equation 456 x y - 1 = 0

456 (x^{'} \times \frac{2}{2} - y^{'} \times \frac{2}{2}) (x^{'} \times \frac{2}{2} + y^{'} \times \frac{2}{2}) - 1 = 0

Calculate

More Steps

228 (x^{'})^{2} - 228 (y^{'})^{2} - 1 = 0

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

228 (x^{'})^{2} - 228 (y^{'})^{2} = 0 - (- 1)

If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses

228 (x^{'})^{2} - 228 (y^{'})^{2} = 0 + 1

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

228 (x^{'})^{2} - 228 (y^{'})^{2} = 1

Use a = \frac{1}{\frac{1}{a}} to transform the expression

\frac{( x ^{'} ) ^{2}}{\frac{1}{228}} - 228 (y^{'})^{2} = 1

Solution

\frac{( x ^{'} ) ^{2}}{\frac{1}{228}} - \frac{( y ^{'} ) ^{2}}{\frac{1}{228}} = 1
