What is TI?
The machine you are holding is the graphic calculator of Texas Instruments, or TI-83 for short, which is the designated examination machine for studying abroad. In the SAT/ACT/AP/IB exam, it is stipulated that this machine can be used to assist calculation.

Suitable for overseas students and students from domestic and international schools (this model is the designated model for various exams, such as SAT and AP exams);

Suitable for junior and senior high school students to study and explore mathematics;

Combined with CBL2 data collector, it is suitable for collecting and processing experimental data of physics and chemistry students in universities and middle schools (especially outdoor experiments).

It is suitable for staff engaged in data statistics, complex calculation and other related fields.

Brief introduction of main functions

TI-83Plus graphic calculator is a learning tool specially designed for middle school students to study mathematics and physics. It is easy to use and provides all the functions needed for middle school math and science courses. At the same time, it also has advanced statistical and financial functions.

Due to the use of flash memory technology, application software (i.e. Apps) or functional modules other than mathematics and science can be installed on TI-83Plus, thus expanding application functions and facilitating long-term use.

Main functions of TI-83 Plus

algebraic operation

Fast processing includes algebraic operations such as digital operations, symbolic operations, angle operations, relational operations, matrix operations, equation solving, and solving derivatives and integrals.

Drawing function

Various function images can be drawn, such as scatter diagram, rectangular coordinate diagram, function images given in parametric coordinates and polar coordinates, histogram, block diagram and normal probability curve. Images and tables can be displayed on the same screen.

Besides, you can also create other vivid pictures according to your own imagination.

Image analysis function

By displaying and processing the function image, we can intuitively reflect the relationship between related variables, and interactively analyze the function value, vertex, maximum, integral and derivative.

Data statistics and regression analysis

The input data can be sorted, combined and statistically calculated, and the results can be displayed in graphic or digital form. Powerful regression analysis function can fit the data as a whole, which is convenient for processing series.

data acquisition

Use CBL2, CBR applications and external sensors built in TI-83 Plus, and external data (time, distance, temperature, voltage, luminosity, etc. ) can collect and analyze in real time to help students explore the real world!

Financial function

This calculation includes advanced statistical functions such as VTM, asymmetric cash flow and installment payment.

Program function

You can program yourself according to the algorithm.

TI-83 Plus application software

Application software (Apps) provides additional functions for the graphic calculator. Select many applications we currently provide (visit our website frequently to get news of newly added applications) and install special functional modules for TI-83 Plus. The installation process of application software is very simple, just like adding a program to a computer. Because TI-83 Plus has a huge storage space of 160K, you can store as many as 10 applications at the same time-so your calculator can meet your special needs.

TI-83 Plus is pre-installed with the following application software.

Finance (finance)

Data acquisition (CBL new protocol? /CBR)

Probabilistic simulation (probabilistic simulation)

Scientific tools (scientific tools)

Study card (study card? Use a new stack)

Upgradeable operating system

TI-83 Plus will be your best long-term investment. We promise to provide upgrade service for its operating system, and the increased performance and functions will enable your TI-83 Plus to serve you for many years. Connecting with personal computer with TI-GRAPH LINK
