Ti-84 plus Graphing calculator - Black

Real and complex numbers are computed to 14-digit precision and shown with 10 digits plus a 2-digit exponent. It graphs 10 rectangular functions, 6 parametric expressions, 6 polar expressions, and 3 recursively-defined sequences. As many as 10 graphing functions can be defined, saved, graphed, and analyzed simultaneously. Sequence graphing mode displays time series plots, cobweb/stair-step plots, and phase plots. It features user-defined list names. Lists can hold up to 999 elements. It contains 14 interactive zoom features. Numeric evaluations are provided in table format for every graphing mode. It enables interactive analysis of function values, roots, maximums, minimums, integrals, and derivatives. It offers 7 distinct graph styles to differentiate the appearance of each graph drawn. It provides horizontal and vertical split-screen options. It stores up to ten 50x50 matrices. It performs matrix operations including inverse, determinant, transpose, augment, reduced row echelon form, and elementary row operations. It converts matrices to lists and vice-versa. It conducts list-based one- and two-variable statistical analysis, including logistic, sinusoidal, median-median, linear, logarithmic, exponential, power, quadratic polynomial, cubic polynomial, and quartic polynomial regression models. It includes 3 statistical plot definitions for scatter plots, xy-line plots, histograms, regular and modified box-and-whisker plots, and normal probability plots. It features advanced statistics with 9 hypothesis testing functions, 6 confidence interval functions, and one-way analysis of variance. Features: Over 200 functions and a multi-line display
