When a problem of physical science appears it's either surprisingly observed data or a textbook (scholastic) problem, be it of the natural type (solar, geological, astronomical), the solution lies in identifying the system in subject as one which has an orthodoxy, and which is why we need the motivations of the phenomenological information, along with the mathematical rigor giving us more to worry about, which is physics + mathematics.
An introduction to these articles, with some set notation and the field of real numbers. First article
An end to the mathematical frustration of man comes with anaylsis of the binomial (1620), and the generalization of the formula to a series solution of the binomials with non-natural number exponent (1665). Ancient functions
The oldest series, being described in Euclid's Elements, has a wide range of applicability. Geometric Series
Exponents are a simple algebraic construction and notation; they are used in scientific notation and are implicit in the decimal notation. Roots are an intrinsic part of exponents (the fractional exponents). So, in this section the "original" exponent value (zero) is explored. Zero Exponent and Roots
The logarithm is presented as an 18th century revelation. The natural exponential is compared to other exponential bases, graphically. Natural exponent
If the summation of a series grows faster than some rate, then it diverges. Up until the 17th century, no one knew whether the Harmonic Series diverged, or converged, as it grows very slowly, but faster than the Geometric series.
Tangents in general are considered, particularly those of curves which come to the minds of early modern natural philosophers. Tangents and their Calculus
The inverse operation of the tangent of a curve, is the summed area under such function. Integral as Inverse of Tangent
In the modern frameworks, a ubiquitously appearing tool, is the representation of a any curve in terms of a polynomial with differential coefficients. Taylor Series
