It 'easy interactive graphing calculator to find Web sites, but finding a free, easy to use graphical applet calculator that is not buggy a greater challenge. One of the best is at Utah State University NLVM hosted by the National Library of Virtual manipulatives. If you are not familiar with it, NLVM is a vast collection of interactive applets for students and teachers. You will find no shortage of interesting puzzles and games out there, but this time we wanted to emphasizetheir "Grapher" applets.
What distinguishes the NLVM Grapher is easy to use yet powerful interface. You can easily use to use the menu at the top of the screen for fractions, exponents, square roots and absolute values, all of which can only be entered as they appear in a textbook. There is very little confusion on the screen to intimidate users.
There are a staggering number of options for a computer based on Java. Of course there is a simple track, which uses a cursor.There are three additional tabs for users to choose the parameters and functions of the windows.
Parameters, the user can lay up to three parameters of the equation that can be changed with a slider. If you are interested in checking translations, this is a very powerful feature, because it fits the graphics in real time.
It is not surprising given the set of windows users to view the video again. Fortunately, you can also just use the mouse to zoomSelect a region to see.
The feature card provides the user the ability to insert up to three functions. One of the really nice features here is that the composite functions are supported (even if they are inverse functions). Other advanced features offer the possibility to choose the color of the individual functions and to limit the domains.
The applet does not contain all the features of a high-end handheld graphing calculator, but that's not the point. If you use a student to tryGraphics for the first time or a teacher in the classroom implementation, is a simple and reliable solution. NLVM Grapher is one of the best graphic calculators is now available online.
