Mathematics:
Its Not Just Arithmetic
Sarah Portier, University of Florida
February 14, 2002There are
many fields of math above and beyond the ones every student is taught. Arithmetic, the use
of the processes of addition, subtraction, multiplication, and division, is a necessary
stepping stone for the working of other forms of math, but every field has its own
purposes and processes. You are likely to come across these fields in high school and
college:
Algebra: The name comes from an
Arabic word, al-jabr, meaning "the reduction." Algebra is an extension of
arithmetic where letters are used to replace numbers. These letters can represent a simple
unknown number or an abstract concept such as complex numbers, matrices, sets of numbers,
and vectors.
Geometry: Named for the Greek word
for "to measure the Earth," geometry deals with points, lines, angles, and
shapes their measurement, properties and relationships. Plane geometry is in a flat
surface, and solid geometry deals with three-dimensional objects in space.
Trigonometry: Closely related to
geometry, trigonometry is the study of angles, which is the origin of its name (which
means "the measure of three angles"). The basic concept is the trigonometric
functions of sine, cosine, and tangent, which are ratios between the lengths of the sides
of a right triangle.
Analytic Geometry: Also called
coordinate geometry, analytic geometry is the study of geometric properties by use of
algebraic functions and a coordinate system. In short, it defines geometrical ideas in
terms of algebra.
Calculus: With a name taken from the
word for "stone," calculus rests on two basic concepts: the derivative, which is
the slope of a line at any point on a graph, and the integral, which is the area under a
curve. Calculus is used when variables are changing, to determine rates of change, effects
of changes, maximum and minimum values, areas and volumes of shapes, and other
characteristics of functions.
Statistics: Statistics deals with
the collection, analysis, interpretation, and presentation of masses of data. |
