Mathematics isn't all about number crunching. If it were, we could leave the job to computers and never learn another stitch of math. Mathematics is really about thinking analytically and then modeling, portraying, and predicting events ... both real and imaginary. - DLH

Pre-calculus is a catch-all term for a series of studies that are initially expressed in the language of algebra and leading to expressions of basic calculus.  It is a necessary step in the progression of mathematics education, from arithmetic through calculus.


Sometime after completion a calculus program, lifelong learners ought to return to the subject, but this time going deeper into its two main topics Trigonometry and Geometry.

Trigonometry is a branch of mathematics that studies the relationships between the sides and the angles in triangles. Trigonometry defines the trigonometric functions, which describe those relationships and have applicability to cyclical phenomena, such as waves.

In classical mathematics, analytic geometry, also known as coordinate geometry or Cartesian geometry, is the study of geometry using a coordinate system. This contrasts with synthetic geometry.

Analytic geometry is widely used in physics and engineering, and also in aviation, rocketry, space science, and spaceflight. It is the foundation of most modern fields of geometry, including algebraic, differential, discrete and computational geometry.
