HighEnd Graphic Calculators c2013


Unless
you use handheld calculators on a regular basis, you might be inclined
to wonder why someone wouldn't simply use a computer, tablet, smartphone,
etc., for routine calculations. After all, the software available for
and the computational power of even a nothingspecial computer greatly
outperforms the most powerful handheld calculator, right? The simple
answer is that when you are working in a confined space as is often
the case at a classroom desk or in a research and development lab, finding
a place to sit down and use a notebook or tablet computer can be challenging.
There is also an advantage in having a device specially built with a
custom ASIC and populated with optimized software that covers a wide
range of computational needs. Equivalent mathematical and graphical
capabilities of some highend calculators  such as fitting a curve
over a graphical background image  can only be found in computerbased
software that costs as much or more than a calculator. USB interfaces
and in some cases WiFi connectivity makes transferring data to/from
the calculators easy for use in reports, further research and printing.
Often, computerbased software that emulates the calculator functionality
is available for use for classroom instruction or to be able to use
while back in the office. BTW, these highend calculators are interchangeably
referred to as "graphing" or "graphic" calculators because they support
graphic images (icons, symbols, and usersupplied) as well as chart
plotting. Christmas is coming and you might be trying to figure out
what to get your favorite student, engineer, scientist, mathematician,
accountant, or hobbyist this year. A new calculator would make a perfect
stocking stuffer. I found what appears to be the topoftheline, stateoftheart
handheld calculators on the markets as of November 2013 (see below).

Hewlett Packard
Prime Graphing Calculator
HPPrime™ is a featurerich calculating experience with familiar
HP keypad and a large 3.5inch diagonal, multitouch full color
display. Explore math concepts with Dynamic Geometry, CAS, Advanced
Graphing, and spreadsheet applications. HPPrime™ employs familiar
RPN, Algebraic and textbook entry system logic. HPPrime™ comes
with an integrated tool suite: HP Equation Writer supports multiple
linear and nonlinear equation solving. HP Solve is timesaving
application that allows you to store equations and solve for
variables. Easily switch between symbolic, graphical, and numerical
table views with dedicated buttons. Instructors can turn the
calculator into a testing tool with TestMode configuration
that makes only preapproved functions available.

Casio
Fxcg20 Graphic Calculator
Picture Plot enables users to create their own graphs over
pictures displayed on the color LCD. The fxCG10/20 comes with
55 types of color pictures that users can create graphs over,
such as a picture of the parabola of jets from a water fountain
and an image sequence of a clock’s pendulum movement. Users
can perform regression calculations from the completed graphs
to enhance their understanding of math functions. Expanded matrix
allows addition of vector processing features. Makes learning
exactly according to your textbook possible. Addition of population
standard deviation, population variance and new random commands.
