SUBTANGENT Meaning and
Definition
-
Subtangent is a term commonly used in the field of calculus to describe a specific geometric property of a curve or function, particularly in relation to the graph of a function. It refers to a line segment that touches the curve at a single point and is parallel to the tangent of the curve at that particular point.
More precisely, the subtangent is defined as the perpendicular distance between the x-axis and the tangent line at a given point on the curve. It represents the slope of the tangent line at that point and provides information about the rate of change of the function at that particular point.
In mathematical terms, the subtangent can be calculated by finding the difference in y-coordinates between the point of tangency and the point where the tangent line intersects the x-axis. This measurement is made along a line that is perpendicular to the x-axis.
The subtangent is an important concept in calculus as it helps in determining the instantaneous rate of change of a function, providing insights into the behavior of the curve at a specific point. It is used in various applications, such as optimization problems, finding points of inflection, and analyzing the concavity or convexity of a curve. By understanding and calculating the subtangent, mathematicians and scientists can better comprehend the behavior and characteristics of functions, enabling them to make more accurate predictions and solve complex mathematical problems.

Etymology of SUBTANGENT
The word "subtangent" is derived from the combination of two Latin words: "sub" meaning "under" or "below", and "tangens" meaning "touching". In mathematics, the term "subtangent" refers to a line segment drawn from a point on the curve of a function to the x-axis, making a right angle with the tangent line at that point. The "sub-" prefix signifies the line segment being below or under the tangent line.
