Texas InstrumentsGraphic Calculator 184Kb TI83 Plus

I bought this calculator for my daughter who is doing her A level maths as it is one that is allowed in the exam itself .... it saves a lot of time plotting by hand graphs. She found it easy to use too.

My son was very pleased with this

Good

It was new but so dusty

I am a Head of Mathematics at Davison High School and an advanced skills teacher. We have used the TI 83 and TI83plus for some time with our students. I also visit local primary schools and use them with younger students. They love the graphs, pie charts and probability applications.Graphing becomes accurate and exciting. Calculations promote discussion using the screen projector. Handling data is developed so that students can interepret and think rather than just calculate. The facility to download from the internet enables us to use exciting applications. We can simulate rolling dice, flipping coins and can solve equations and draw graphs and charts.The link facility enables students to print their work or transfer screens to Word and so include this in their GCSE coursework. This has really enabled us to turn Ds into Cs and As inot A*s. Many students want to buy their own calculator. A student today returned from the sixth form college with the calculator she used with us. She has said on many occasions, I really like my calculator. She came back to say how well things were going in the sixth form.We are developing work with rangers which enable us to draw real-time graphs and collect and process real data. And now TI I have brought out TI interactive we can link the calculator not only to the internet but also to our PCs. And what's more if I can do it it can't be difficult.This calculator has really enhanced my teaching and supported the learning of the students. They can work individually or in pairs. Ideal too for both teacher demos and students' individual work. Suits the shy students as well as the computer wiz. Thears's so much on the calculator. It is fascinating and at the same time easy to get started with (great handbook too). Great stuff.

wow

Some of the important buttons don't work

Showed up the next morning right when I needed it, comes with batteries and works perfectly.

Me llegó muy rápido y en excelentes condiciones.

The TI-83 Plus is an older model of programmable scientific calculator. This is the 4th one we each use. I am an electrical engineer, and my wife is working in medical nutrition at the clinical level.We each both need a practical type of calculator for being able to quickly solve equations we each commonly use. Her applications are in the bio-medical field, and mine is with solving electrical engineering problems. We each have over 20 different formulas written in to our calculator. We also keep a calculator on hand as a spare in case one of these fail.I was able to write the software coding based on required formulas and save it to this model of calculator. We have the original detailed instruction books for this calculator giving examples of the coding and process about how to write software in to this model type. It is fairly involved, but works out very well. This calculator model is a very advanced type for its size and gets the equations easily and quickly solved. It is much more convenient for portability than using Excel or some other type of math software on a laptop.We have the TI calculator management software installed in our computers, and can back up the calculator's programs to the computer's data drive. We have been using this model of calculator since it came out and being used to it and very proficient with this model, makes our preference is to not change the model. There is a newer equivalent version with advancements for the display and etc.We have been using this model of calculator sometimes every day since 1998 when they came out. Over the years with use they have eventually failed. Sometimes the calculator may be dropped, and over time with use there are wear factors involved. With near daily use and for at least an hour or more per day we are getting about 4 to 6 years of use from each calculator. This is terrific.The memory battery lasts about 3 years average in these. This is not difficult to change. The main batteries last about 6 months to 1 year with daily use. There is a procedure to allow the memory battery to be changed without losing the programs stored in calculator.With the data transfer cable that comes with the calculator it is possible to back up the calculator's programming and variables to another one like it. There is also the silver USB type interconnect cable that allows this calculator model to be backed up to a computer using the TI calculator management software.

Very high quality, for a high price.

Ottima calcolatrice grafica che svolge esercizi di algebra lineare (matrici, determinanti ecc), statistica (media, standard deviation...) e analisi ( derivate, integrali definiti, studio di funzione, asintoti, intersezione con gli assi, punti di flesso, punti di massimo e minimo ecc). C'è da dire che con le derivate e gli integrali la calcolatrice mostra soltanto il risultato finale e non tutti i passaggi (non è step by step), peró comunque è utile per vedere se il proprio risultato è corretto e coincide con quello della calcolatrice. Non è cas. Non si puó collegarla al computer. Utile per le classi quinte superiori e all'università. Ho imparato ad usarla guardando molteplici tutorial su youtube in inglese, comunque su internet si dovrebbero trovare facilmente le istruzioni per l'uso in italiano sotto forma di pdf. Ottimo acquisto, consigliata. Arrivata in tempo per il mio esame di analisi.
