### Mathematical Curves and their Graphs

Below is a list of mathematical equations representing various curves, along with the respective graphs and details.

#### 27. Hyperbola
Equation: \( x^2 - xy - y^2 = 1 \)
Point: \((2, 1)\)

#### 28. Ellipse
Equation: \( x^2 + 2xy + 4y^2 = 12 \)
Point: \((2, 1)\)

#### 29. Cardioid
Equation: \( x^2 + y^2 = (2x^2 + 2y^2 - x)^2 \)
Point: \((0, \frac{1}{2})\)

- **Graph Description**: The graph shows a rounded curve resembling a heart shape with a cusp at the origin. It is symmetric about the x-axis.

#### 30. Astroid
Equation: \( x^{2/3} + y^{2/3} = 4 \)
Point: \((-3\sqrt{3}, 1)\)

- **Graph Description**: This is a four-cusped shape symmetric about both the x- and y-axes. The curve touches the axes at four points, forming a star-like shape.

#### 31. Lemniscate
Equation: \( 2(x^2 + y^2)^2 = 25(x^2 - y^2) \)
Point: \((3, 1)\)

- **Graph Description**: The graph is shaped like a figure-eight or infinity symbol, centered at the origin, symmetric about both axes.

#### 32. Devil's Curve
Equation: \( y^2(y^2 - 4) = x^2(x^2 - 5) \)
Point: \((0, -2)\)

- **Graph Description**: This complex curve has multiple loops and is symmetric about both the x- and y-axes. The shape features intricate crossings and central symmetry.

These equations and their graphs illustrate a variety of interesting mathematical curves, showcasing symmetry, intersections, and unique properties associated with each form.
