Client Reviews
Strengths:
The document management method -- many "problems" can be kept in the calculator at the very same time, and each predicament keeps its personal variable names beneficial graphing capabilities ability to split the screen and function with several views of the identical issue spreadsheet application. The calculator has 5 "applications" (calculator, graphs geometry, spreadsheet, data statistics, notes), and specifics can be shared among them.
Weaknesses:
The documentation is extremely poor. There are two user guides, with considerable overlap in the contents. In User Guide Portion 1, which comes packaged with the calculator, there are 25 pages on the Graphs Geometry application, and the data on how to truly plot a graph is barely mentioned. User Guide Element two comes as a PDF file, and has a lot more detail, but is badly organized and missing a lot of data. For example, directions for a number of operations say to "drag" something, but nowhere in the manual does it say how to do that.
Keypad: other reviewers have commented on the difficulty pressing the ideal buttons on the keypad. Even worse is the "mouse" operation. I finally found that dragging involves holding the center "Click button" when pressing the arrow keys on the "NavPad". It is extremely hard to control the cursor with the NavPad, and doubly so when attempting to hold down the click button. Also, what operation is carried out by a click or drag is dependent on exactly where on the screen the cursor is, and it's complicated to control the cursor location with the level of precision required.
TI-84 compatibility: This seemed like a excellent thought. Yet, as far as I can ascertain, there's no way to integrate TI-84 functions with TI-Nspire functions. When you put in the TI-84 keypad, you get a TI-84. With the TI-Nspire keypad, you get a TI-Nspire. If you want to transfer details from one particular to the other, it seems to be impossible. The only pertinent data in the documentation about TI-84 mode is a warning that if you update the operating program, all your added TI-84 applications will be deleted.
Lack of software program: The TI-84 has a lot of user-contributed software program. There is virtually nothing at all on the TI internet web-site for the TI-Nspire. I also didn't locate considerably with a net search, and some of what is accessible requires the CAS version. For example, there do not seem to be any built-in physical constants or conversion elements for units. I could switch to TI-84 mode and get them, but then what's the point of purchasing the TI-Nspire?
Summary:
This calculator does not appear to be nicely-engineered or nicely-supported by TI. I would advocate waiting to see whether they give it the help that it deserves.
This calculator offers SOME improvements over earlier models. I discover the statistical functions, specifically regressions and distributions, and the calculus functions to be far far more intuitive. You do not have to keep in mind all the parameters required to use these functions. The menus are incredibly effortless to have an understanding of and I do not obtain myself operating to an inadequate support manual as I did on earlier calculators.
The higher resolution and larger screen give a substantially nicer presentation. Concerns are entered and solved in text just about precisely as you would see in a book. Graphs also look far more correct and detailed.
But there is 1 thing I DO NOT like on this calculator....THE BUTTONS The letter keys are compact green keys nestled among the quantity and function keys. Therefore you are constantly hitting the letter keys by accident and so you have to waste time correcting typing errors.
An additional large unfavorable for me is the awkward nature of the graphing screen when obtaining roots, max/min points, and points of intersection. To uncover roots as nicely as max/min points you have to trace along the graph and when the tracer arrives at the point it provides the coordinates on the screen. Having said that, the coordinates are often conflicting with the similar space as the graph itself and hence you cant study the point. So you have to grab the coordinates and drag them to a spot on the graph exactly where you can see it. And if you occur to trace past the point too promptly, the coordinates disappear and you have to trace back once again. The very same procedure applies to max/min points. Locating graph facts with the TI84 and TI89 is far less difficult and quicker.
I also think the snap on keyboard that converts the calculator to an 84 will at some point prove to be a bad idea. How quite a few of those keyboards are going to get broken or lost?
General a decent calculator if you are willing to deal with some upfront frustration. But I do not see adequate benefits yet to pick this more than an 84 or an 89.
