The Inequality ∣z−4∣ \textless ∣z−2∣|z-4|\ \textless \ |z-2| Represents the Region Given by

In mathematics, inequalities involving absolute values are used to describe regions in the complex plane. The inequality ∣z−4∣ \textless ∣z−2∣|z-4|\ \textless \ |z-2| is a specific example of such an inequality, where zz is a complex number. In this article, we will explore the region represented by this inequality and provide a detailed explanation of its geometric interpretation.

To begin with, let's understand the inequality ∣z−4∣ \textless ∣z−2∣|z-4|\ \textless \ |z-2|. Here, zz is a complex number, which can be represented as z=x+yiz = x + yi, where xx and yy are real numbers, and ii is the imaginary unit. The absolute value of a complex number zz is defined as ∣z∣=x2+y2|z| = \sqrt{x^2 + y^2}.

The inequality ∣z−4∣ \textless ∣z−2∣|z-4|\ \textless \ |z-2| can be rewritten as ∣z−4∣2 \textless ∣z−2∣2|z-4|^2 \ \textless \ |z-2|^2. Expanding the squares, we get (x−4)2+y2 \textless (x−2)2+y2(x-4)^2 + y^2 \ \textless \ (x-2)^2 + y^2.

To simplify the inequality, we can expand the squares and combine like terms. This gives us:

(x−4)2+y2 \textless (x−2)2+y2(x-4)^2 + y^2 \ \textless \ (x-2)^2 + y^2

Expanding the squares, we get:

x2−8x+16+y2 \textless x2−4x+4+y2x^2 - 8x + 16 + y^2 \ \textless \ x^2 - 4x + 4 + y^2

Combining like terms, we get:

−8x+16 \textless −4x+4-8x + 16 \ \textless \ -4x + 4

Subtracting −4x-4x from both sides, we get:

−4x+16 \textless 4-4x + 16 \ \textless \ 4

Subtracting 16 from both sides, we get:

−4x \textless −12-4x \ \textless \ -12

Dividing both sides by -4, we get:

x \textgreater 3x \ \textgreater \ 3

The inequality x \textgreater 3x \ \textgreater \ 3 represents the region to the right of the line x=3x = 3. This means that any complex number zz that satisfies the inequality ∣z−4∣ \textless ∣z−2∣|z-4|\ \textless \ |z-2| must lie to the right of the line x=3x = 3.

To visualize this region, we can plot the lines x=3x = 3 and x=4x = 4 on the complex plane. The line x=3x = 3 is a vertical line that passes through the point (3,0)(3, 0), while the line x=4x = 4 is a vertical line that passes through the point (4,0)(4, 0).

The region represented by the inequality ∣z−4∣ \textless ∣z−2∣|z-4|\ \textless \ |z-2| is the area to the right of the line x=3x = 3 and to the left of the line x=4x = 4. This region is bounded by the two vertical lines x=3x = 3 and x=4x = 4, and it extends infinitely in the positive yy-direction.

In conclusion, the inequality ∣z−4∣ \textless ∣z−2∣|z-4|\ \textless \ |z-2| represents the region given by the area to the right of the line x=3x = 3 and to the left of the line x=4x = 4. This region is bounded by the two vertical lines x=3x = 3 and x=4x = 4, and it extends infinitely in the positive yy-direction.
