Exploring the Equation: (x-1)^2 + y^2 = 16

The equation (x-1)^2 + y^2 = 16 represents a circle in the Cartesian coordinate system. Let's delve into understanding this equation and its key properties.

Understanding the Equation

The equation is in the standard form of a circle:

(x - h)^2 + (y - k)^2 = r^2

Where:

  • (h, k) is the center of the circle
  • r is the radius of the circle

In our equation:

  • (h, k) = (1, 0), indicating the center of the circle is at the point (1, 0).
  • r^2 = 16, meaning the radius of the circle is r = 4.

Visualizing the Circle

To visualize the circle, plot the center point (1, 0) on the coordinate plane. Then, from this center point, draw a circle with a radius of 4 units.

Key Properties

Here are some key properties of this circle:

  • Center: (1, 0)
  • Radius: 4
  • Diameter: 8
  • Circumference:
  • Area: 16π

Applications

Understanding circles and their equations is fundamental in various fields, including:

  • Geometry: Analyzing geometric shapes and their relationships.
  • Trigonometry: Calculating distances and angles using trigonometric functions.
  • Physics: Describing circular motion and orbits.
  • Engineering: Designing structures, machines, and systems.

Conclusion

The equation (x-1)^2 + y^2 = 16 represents a circle centered at (1, 0) with a radius of 4. This understanding opens doors to exploring various mathematical concepts and applications related to circles.
