***FEATURED TOOL
Tool: Math Visual Solver
http://mathforum.org/mathtools/tool/125073/
John Linstrum
This open source Java software takes a basic algebra equation,
inequality, or expression, and solves, simplifies, or factors
it, displaying step-by-step explanations in an adjacent window
and highlighting affected terms along the way. Also try it to
simplify a numerical expression (without variables).

***FEATURED TOOL
Tool: The Trajectory of a Cannonball
http://mathforum.org/mathtools/tool/125632
Paul Trow
Plot the trajectory of a cannonball for a given muzzle velocity
and angle of elevation.

***FEATURED TOOL
Tool: WebGrapher
http://mathforum.org/mathtools/tool/125090/
Tom Cooper
This page contains a graphing applet that can be used online or
that can be saved as web pages. Users can plot points, functions,
parametric functions, polygons, vectors and more. There are
examples from Algebra, Trigonometry, Calculus, Geometry, and
Math for Teachers.

***FEATURED TOOL
Tool: Roman-Numerals.org
http://mathforum.org/mathtools/tool/125082/
John Barth
Lessons, worksheets, online games, and quizzes for practicing
Roman numeral counting and arithmetic. Sections accessible from
the left sidebar include Making Roman Numerals, Learning Roman
Numerals, and Roman Numerals Resources.

***FEATURED TOOL
Tool: Problems with the Trapezoid
http://mathforum.org/mathtools/tool/125634/
Bill White
Problems are generated requiring the user to find the area or
length of one of the bases or the height of a trapezoid. The
interesting feature of this program is that it doesn't restrict
the problem to just finding the area of the trapezoid. The
unknown may be the area, but it also may be either base or the
height. This requires the person solving the problem to think
about how to use what they know to find that unknown value.

***FEATURED TOOL
Tool: ShowTheMath.org
http://mathforum.org/mathtools/tool/125080/
Alan Degener
Enter an algebraic equation and then solve it, step by
step -- manually: use the pull-down menu to describe steps as
combining like terms, distributing, expanding, factoring, adding
to both sides, subtracting from both sides, dividing both sides,
multiplying both sides, taking a root of both sides, or raising
both sides to a power. ShowTheMath.org allows LaTeX
typesetting commands.

***FEATURED DISCUSSION
Calculus without calculus
LFS explains, "I want my (non-math) IT kids to do the cool
things from calculus but without having to know calculus."

***FEATURED TECHNOLOGY POW
