MathTutorDVD.com has posted two additional lessons in the
differential equations course that is currently in development.

Lesson 7 – Existence and Uniqueness Theorem
Lesson 8 – Graphing Solutions of ODEs

I will release Vol 1 of the Differential Equations tutor in about
a month that will be around 9 hours in duration and will
cover the solution techniques and applications of first
order differential equations.  Vol 2 will cover second order
and higher differential equations and applications!

MathTutorDVD.com has posted a partial list of
schools, libraries, and universities that use our
school DVD series in the classroom.  A wide
range of institutions use the DVD series from
well known universities such as MIT, to smaller
public school systems around the country.

These are the very same DVDs available at
MathTutorDVD.com and are being used by
thousands of students around the world!

MathTutorDVD.com – We’ve just released a new tool on the
website that allows you to interactively view the
vector components of a vector.

Decomposing a vector is an extremely important topic for
all math students to master, and is used in all higher classes
such as Trig, Calculus, Physics, and all levels of Engineering.

Understanding this topic is easiest when we discuss motion
of an object in the presence of gravity.  If we throw a ball at
an angle to the ground we discover that the motion is a
curved arc.  This motion is fairly complicated but it can be
simplified a great deal by performing vector decomposition
to break the vector up in to “x”and “y” components.

When we do this, we can calculate the motion along the
vertical direction (y-direction) and separately along the
horizontal direction (x-direction).

We can then calculate the motion in these directions
separately which is much easier than trying to use
Newton’s laws to calculate the motion in both directions
at the same time.

Math Tutor DVD has posted a free tool to help students
visualize the concept of line slope in Algebra.  The
student simply enters in any two points in the x-y plane
and the tool will calculate the slope between these two
points and graphically draw a graph of the line passing
between these two points!

Math Tutor DVD has created an interactive way
to learn about derivatives in calculus.  The student
enters any function right into the web page and
then the student is shown what the derivative of
that function is along with its
derivative graph!

Math Tutor DVD  has created an interactive
PreCalculus Unit Circle that graphically shows
the unit circle along with the Sin and Cos of any
angle that the user inputs.

As you select the input angle the interactive graphic instantly
shows the student the projection of the angle onto the x-axis
(showing Cosine) and the y-axis (showing Sine).

Hi, I have begun a section of MathTutorDVD.com related
Mathematica Tutorial Videos.

Wolfram Mathematica is one of the most powerful math
software programs in the world.  Mathematica can handle
graphing, algebra, geometry, advanced calculus, and is
frequently used in the science and engineering fields.

This section contains  a set of Mathematica Tutorial
videos designed to teach you Mathematica quickly and
easily.  Mathematica has thousands of functions and
commands and can seem quite complicated to use for
the beginning user.

Our Mathematica Tutorial Videos are designed to get you
up to speed quickly so that you spend less time fiddling
with the program and more time using it.

If you would like to learn mathematica, this is the place!

Over the years students, parents, and teachers have
asked for advice on teaching techniques for teaching
algebra and other subjects.

As a result, I have posted an article with my top 4 tips and
techniques on How to Teach Algebra!

These techniques actually apply to teaching any subject,
and in the future I will post other articles with tips and
techniques!

I have also posted an article on How to Teach Fractions that should be of interest to teachers and parents!

We have posted the next 4 lessons in the
Pre-Algebra section!

Lesson12 – Greatest Common Factor
Lesson 13 – Least Common Multiple
Lesson14 – Introduction to Fractions and Simplification
Lesson 15 –  Mixed and Improper Fractions

Lesson 6 of Differential Equations is posted!

Lesson 6 teaches  “Exact Differential Equations”.
