This renewed version, available in a sleek black finish, maintains the high standards of quality and functionality that Texas Instruments is renowned for.

One of the standout features of the TI-84 Plus is its ability to calculate real and complex numbers with an impressive 14-digit accuracy. The calculator displays results in a user-friendly format, presenting 10 digits plus a 2-digit exponent. This level of accuracy is crucial for anyone involved in serious mathematical computations.

The calculator provides robust graphing capabilities, allowing users to graph up to 10 rectangular functions simultaneously. It also supports 6 parametric expressions, 6 polar expressions, and 3 recursively-defined sequences. For those needing to visualize data points over time, the sequence graphing mode offers various plot types including time series, cobweb/stair-step, and phase plots.

Users can define custom list names and store an impressive number of elements in lists, accommodating up to 999 entries. The TI-84 Plus incorporates 14 interactive zoom features, enhancing the user’s ability to analyze graphs effectively. It also provides numeric evaluations in a convenient table format for all graphing modes, making it easier to interpret data.

Interactive analysis is another strong suit of the TI-84 Plus, enabling users to explore function values, roots, maximums, minimums, integrals, and derivatives. With 7 different graph styles available, users can differentiate the appearance of each graph drawn, ensuring clarity in presentations or studies.

The calculator also offers horizontal and vertical split-screen options, allowing for a more comprehensive view of multiple functions at once. Users can store up to 10 matrices, each with dimensions of 50×50, and perform complex matrix operations including inverse calculations, determinant evaluations, transpositions, augmentations, and reduced row echelon forms. The ability to convert matrices to lists and vice versa provides additional flexibility for users.

Statistical analysis is simplified with the TI-84 Plus, which supports list-based one- and two-variable statistical analysis. It includes various regression models such as logistic, sinusoidal, median-median, linear, logarithmic, exponential, power, quadratic polynomial, cubic polynomial, and quartic polynomial regression models. This makes it a valuable tool for conducting thorough data analysis.

Furthermore, the TI-84 Plus defines 3 statistical plot types, including scatter plots, xy-line plots, histograms, and box-and-whisker plots (both regular and modified). It also features normal probability plots to assist users in understanding data distributions comprehensively.

For those delving into advanced statistics, the calculator is equipped with 9 hypothesis testing functions and 6 confidence interval functions, facilitating one-way analysis of variance. These features cater to advanced mathematical and statistical needs, making the TI-84 Plus an indispensable device for higher education and professional use.
