Locating Points on the Quadrants: In Which Quadrant is the Number –14 – 5i Located on the Complex Plane? I II IIII IV

The number -14-5i is located in the third quadrant of the complex plane.

To locate a point on the complex plane:

1. Represent the real part of the number on the horizontal axis (x-axis), and the imaginary part on the vertical axis (y-axis).

2. The point where the horizontal and vertical axes intersect is called the origin and is represented by the number 0.

3. The complex plane is divided into four quadrants: I, II, III, and IV, moving counterclockwise from the upper right.

4. Determine which quadrant the point is located in by looking at the signs of the real and imaginary parts of the number.

In the case of -14-5i, the real part (-14) is negative, and the imaginary part (-5) is negative. Therefore it lies in the third quadrant.

Remember that the quadrant assignments follow a counterclockwise order:

• Quadrant I is the upper right, Quadrant II is the upper left.
• Quadrant III is the lower left.
• Quadrant IV is the lower right.

Understanding the Complex Plane System

The complex plane system is a two dimensional graph viewed from an x-axis and y-axis. In this graph, we use imaginary numbers to identify points in the plane. Each point is assigned a number related to a specific quadrant.

Let’s understand the rules for determining the quadrant a given number is located in.

Definition and Explanation of Complex Plane

The complex plane, or the Argand plane, is a graphical representation of complex numbers. It is a two-dimensional coordinate system where the horizontal axis represents the real part of a complex number, and the vertical axis represents the imaginary part.

To locate a complex number on the complex plane, we plot its real and imaginary parts as coordinates. For example, to locate the number -14-5i, we plot -14 on the real axis and -5 on the imaginary axis.

The number -14-5i is located on the third quadrant of the complex plane where the real part (x) is negative, and the imaginary part (y) is negative. It is worth noting that complex numbers in different quadrants have different properties, such as their signs, magnitudes, and directions. This is useful in various applications, such as engineering, physics, and mathematics.

Locate the Real and Imaginary Axes

The complex plane system is a mathematical tool that helps represent complex numbers and their operations graphically. It’s composed of two axes, the real, and the imaginary, intersecting at the origin point forming four quadrants on a plane.

To locate a point on the plane, you must determine its real and imaginary components, represented as (a, b) in the form a+bi.

In our example, the complex number -14-5i has a real component of -14 and an imaginary component of -5. Since the real component is negative, the point falls on the plane’s left side, either in quadrant II or III. Since the imaginary part is also negative, the point must fall in the bottom-left quadrant, quadrant III, which is the quadrant of negative real and negative imaginary numbers. Thus, the number -14-5i is located in quadrant III of the complex plane.

Identify the Quadrants

The complex plane system is a mathematical tool that helps us visualize complex numbers on a two-dimensional plane. The system is divided into four quadrants, each representing a different sign configuration of real and imaginary numbers. To locate a point on the complex plane, we need to identify the quadrant in which the point falls.

The point -14-5i is located in the third quadrant of the complex plane system. The third quadrant is where the real numbers are negative, and the imaginary numbers are negative.

Quadrant I is where both the real and imaginary numbers are positive. Quadrant II is where the real numbers are negative, and the imaginary numbers are positive. Finally, Quadrant IV is where the real numbers are positive, and the imaginary numbers are negative.

Understanding the complex plane system is essential to solve mathematical problems involving complex numbers and functions.

Locating Points on the Complex Plane

The complex plane is a two-dimensional graph with two perpendicular axes, typically represented as the x-axis and y-axis. Every point on the complex plane can be identified by its coordinates, typically in the form of (x,y). For example, the complex number –14 – 5i is located on the complex plane, but it requires some knowledge of the four quadrants to identify the exact location. Let’s explore the four quadrants and the point’s location in detail.

Identifying the Real and Imaginary Parts of the Complex Number

In the complex number system, a complex number can be represented as a sum of a real and imaginary parts. The real part is the horizontal axis of the complex plane, while the imaginary part represents the vertical axis.

The complex number -14-5i can be located on the complex plane by identifying its real and imaginary parts. The real part of the number is -14, which is located on the negative side of the horizontal axis (pointing towards the left). The imaginary part of the number is -5i, which is located on the negative side of the vertical axis (pointing downwards).

Therefore, the complex number -14-5i is located in the third quadrant of the complex plane, which is the quadrant where both the real and imaginary parts are negative.

Understanding the location of complex numbers is important in many mathematical fields, including engineering, physics, and computer science.

Plot the Complex Number on the Quadrants

When plotting a complex number on the quadrants, it is essential to know which quadrant the number is located on the complex plane to find its real and imaginary parts.

Let us consider the complex number -14 – 5i. To locate this number on the quadrants, we need to plot it on the complex plane, with the x-axis representing the real part of the number and the y-axis representing the imaginary part.

Since the real part is negative and the imaginary part is negative, the number is in the complex plane’s third quadrant. Therefore, the complex number -14 – 5i is located in quadrant III i.e. -x and -y.

Pro Tip: To plot the complex number on the plane, remember that the x-axis represents the real part, and the y-axis represents the imaginary part.

Determining the Quadrant in which the Complex Number is Located

The complex number -14-5i can be located on the third quadrant of the complex plane with coordinates -14 on the x-axis and -5 on the y-axis.

To determine the quadrant of a complex number, we need to plot it on the complex plane (with the real part on the x-axis and the imaginary part on the y-axis) and observe in which quadrant it lies. In this case, we can plot -14 on the x-axis, move five units downwards on the y-axis, and locate the point in the third quadrant.

Understanding the location of complex numbers on the plane is important in various applications of complex analysis, including electrical engineering and physics.

Identifying the Real and Imaginary Parts of the Complex Number

To identify the real and imaginary parts of a complex number, it’s essential to understand the fundamental components of a complex number. Every complex number comprises two parts: a real part and an imaginary part. The real part corresponds to a point on the horizontal axis (real axis), while the imaginary part corresponds to the vertical axis (imaginary axis). For instance, the complex number -14 -5i has a real part of -14 and an imaginary part of -5.

To locate this point on the complex plane, you must label the horizontal axis as the real axis and the vertical axis as the imaginary axis, then plot the point (-14,-5) on the coordinate system.

To determine the quadrant in which the point (-14,-5) is located, you must observe the signs of both the real and imaginary parts. Since both signs are negative, the point is in the third quadrant.
