Understanding Δx: Calculating the Change in a Variable’s Value with Math

Δx

Δx is a mathematical notation that represents the change in the value of a variable

Δx is a mathematical notation that represents the change in the value of a variable. It is commonly used in calculus to denote the change in the value of the variable x. The symbol Δ (delta) represents the change, while x represents the variable itself.

To calculate Δx, you need to have two values of x, let’s say x1 and x2, and then calculate their difference. The formula for Δx is:

Δx = x2 – x1

For example, if x1 = 5 and x2 = 9, you can calculate Δx as:

Δx = 9 – 5
= 4

So, in this case, Δx is equal to 4. It represents the change in the value of x from 5 to 9.
