Introduction

Hyperbolas are a type of conic section that can be used to model a wide range of real-world phenomena, from the trajectory of a projectile to the shape of a satellite dish. In mathematics, hyperbolas are defined as the set of all points that satisfy a specific equation. In this article, we will explore how to convert the equation of a hyperbola from its general form to its standard form, which is a more convenient and useful form for many applications.

The General Form of a Hyperbola

The general form of a hyperbola is given by the equation:

$$Ax^2 + Bxy + Cy^2 + Dx + Ey + F = 0$$

where $A$, $B$, $C$, $D$, $E$, and $F$ are constants. In the case of the hyperbola we are considering, the equation is:

$$4x^2 - 16y^2 + 32x - 32y - 16 = 0$$

Completing the Square

To convert the equation of the hyperbola to standard form, we need to complete the square for both the $x$ and $y$ terms. This involves rearranging the equation to group the $x$ terms and $y$ terms separately, and then adding and subtracting constants to create perfect square trinomials.

First, let's group the $x$ terms and $y$ terms separately:

$$4x^2 + 32x - 16y^2 - 32y = 16$$

Next, let's factor out the constants from the $x$ and $y$ terms:

$$4(x^2 + 8x) - 16(y^2 + 2y) = 16$$

Now, let's add and subtract the necessary constants to create perfect square trinomials:

$$4(x^2 + 8x + 16) - 16(y^2 + 2y + 1) = 16 + 64 - 16$$

Simplifying the equation, we get:

$$4(x + 4)^2 - 16(y + 1)^2 = 64$$

Dividing by the Constant

To get the equation into standard form, we need to divide both sides of the equation by the constant on the right-hand side:

$$\frac{4(x + 4)^2}{64} - \frac{16(y + 1)^2}{64} = \frac{64}{64}$$

Simplifying the equation, we get:

$$\frac{(x + 4)^2}{16} - \frac{(y + 1)^2}{4} = 1$$

Identifying the Values of $h$, $k$, $a$, and $b$

Comparing the equation we obtained to the standard form of a hyperbola, we can see that:

• $h = -4$
• $k = -1$
• $a = \sqrt{16} = 4$
• $b = \sqrt{4} = 2$

Conclusion

In this article, we have shown how to convert the equation of a hyperbola from its general form to its standard form. We used the method of completing the square to rearrange the equation and create perfect square trinomials. We then divided both sides of the equation by the constant on the right-hand side to get the equation into standard form. Finally, we identified the values of $h$, $k$, $a$, and $b$ from the standard form of the equation.

Introduction

Hyperbolas are a fundamental concept in mathematics, and they have many applications in science and engineering. However, they can be a bit tricky to understand, especially for those who are new to the subject. In this article, we will answer some of the most frequently asked questions about hyperbolas, covering topics such as their definition, properties, and applications.

Q: What is a hyperbola?

A: A hyperbola is a type of conic section that is defined as the set of all points that satisfy a specific equation. It is a curve that is shaped like a pair of connected "U" shapes, with the two branches opening in opposite directions.

Q: What are the key properties of a hyperbola?

A: The key properties of a hyperbola include:

• Center: The point at the center of the hyperbola, which is the point that is equidistant from all points on the curve.
• Vertices: The points at the ends of the hyperbola, which are the points where the curve intersects the asymptotes.
• Asymptotes: The lines that the hyperbola approaches as it goes to infinity, which are the lines that the curve is tangent to at the vertices.
• Foci: The points inside the hyperbola that are equidistant from all points on the curve, which are the points that define the shape of the curve.

Q: What are the different types of hyperbolas?

A: There are two main types of hyperbolas:

• Horizontal hyperbola: A hyperbola that opens horizontally, with the asymptotes parallel to the x-axis.
• Vertical hyperbola: A hyperbola that opens vertically, with the asymptotes parallel to the y-axis.

Q: How do I graph a hyperbola?

A: To graph a hyperbola, you need to follow these steps:

1. Identify the center: Find the center of the hyperbola, which is the point that is equidistant from all points on the curve.
2. Identify the vertices: Find the vertices of the hyperbola, which are the points where the curve intersects the asymptotes.
3. Identify the asymptotes: Find the asymptotes of the hyperbola, which are the lines that the curve approaches as it goes to infinity.
4. Plot the curve: Plot the curve by connecting the points on the asymptotes with the points on the curve.

Q: What are the applications of hyperbolas?

A: Hyperbolas have many applications in science and engineering, including:

• Projectile motion: Hyperbolas can be used to model the trajectory of a projectile under the influence of gravity.
• Satellite dish design: Hyperbolas can be used to design the shape of a satellite dish to maximize its gain.

A: The key formulas for hyperbolas include:

• Equation of a hyperbola: $\frac{(x-h)^2}{a^2} - \frac{(y-k)^2}{b^2} = 1$
• Distance from the center to the vertices: $c = \sqrt{a^2 + b^2}$
