PreCalculus Homework Help Secrets
Better PreCalculus Grades-Less Effort
Need Help with Precalculus?
Advanced Algebra just not your 'thing'?
Spending too much time on struggling with Quadratics and Logs?
Well... Help is just a few clicks away !
We will take you through the basics - from understanding
rational and exponential functions and logarithms to polynomials and complex numbers.
Precalculus Dictionary
One of the challenges of mastering a specific area of mathmetics is to know
and understand the specific terms and words routinely used in the
specific discipline. We have put together a Precalculus Dictionary of
basic definitions of all the important terms and words you will need to
understand and master the advanced algebra skills of precalculus.

Rational Functions
A rational function is by definition a fraction in which both the
numerator and the denominator are polynomials. This section starts with
the simplest rational function f(x) = 1/x and proceeds to more complex
rational functions, how to graph them and determine their asymptotes.

Quadratic Functions
Some of the most critically important and useful functions in applied
mathematics are the Quadratic Functions. These functions are of the
general formula f(x) = ax2 + bx +c and are widely used to
create mathematical models of many natural processes and phenomena

Transformations
In many areas higher math it is necessary to
develop graphs of complicated functions. One of the most powerful
techniques in graphing complicated functions is to start with the
simplest element of the function and transform the graph of the simple
function step-by-step. This section shows you the secrets to this powerful technique.

Polynomials
A polynomial is a generalized algebraic expression which contains
only variables with whole number exponents and constants. The general
form of a polynomial of the is f(x) = anXn +
an-1xn-1 + an-2xn-2 + ... +
a0. A first order polynomial (n=1) is a straight line. A
second order polynomial (n-2) is a quadratic function.

Dividing Polynomials
One of the secrets of mastering polynomials is to understand how to
divide one polynomial by another. In this section we show you how to do
this by long division.

Synthetic Division
This section shows you a short cut method to dividing polynomials
which is much simpler and faster than long division.

Complex Numbers
Complex Numbers, sometimes called 'Imaginary Numbers' are defined as any n
umber which contains the square root of -1.

Asymptotes
An asymptote of a function is defined as a line that the function
gets closer and closer to as one travels along the line. The function
is said to 'asymptotically approach' the line.

Exponential Functions
An exponential function is defined as a constant 'a' (a>0) which is
called the base raised to the power of x which is called the exponent.
The general form of the exponential function is f(x) = ax.

Logarithms
A logarithm is an exponent. It is the exponent needed to produce a
specified number. More specifically a logarithm is the exponent to which
a selected number, called the base, is raised to yields the specified
number. For example 103 = 1,000 and 3 is called
the logarithm to the base 10 of 1,000.

Logarithmic Functions
A logarithmic function is any function that contains a logarithm in
at least one term.

Laws of Logarithms
One of the secrets to effectively working wit Logarithms is to master
the specific Laws of Logarithms which are simply the rules for carrying
out the basic operations of arithmetic on Logarithmic Functions.
