ZFrac1/3, ZFrac 1/4, ZFrac1/5, ZFrac 1/8, ZFrac1/10: These commands graph your function in a preset viewing window and work in the same manner as ZFrac1/2 does.Do not confuse rref( with ref(.Pressing the DEL key instead of clear will delete the list from the calculator.Tracing with these commands let you trace texas the x -coordinates by multiples of 1/.To calculate 3A, press 3 * matrx .A new manual, either hard copy or electronic version, is available from.Clear a sequence definition: Y Place the cursor on the formula, press clear Enter a series: creator Y Use u for the sequence of individual terms and v for the sequence of partial sums.Quadratic, Cubic, Exponential, Power, and other regressions are available on the stat calc menu.Example: to enter the series, enter the following values: n Min 1; u( engineering n ) 1/ n 2; u( n Min) manual 1; v( n ) v( n -1)u( n -1 v( n Min).The TI-84 Plus C graphing rolling calculator not only helps you make player graphs, but its Zoom commands also help you highlight specific areas of a graph, redraw graphs in certain ratios, and otherwise tweak graphs to suit your needs.ZTrig: Draws the graph in a 11 /4 x 11 /4 and 4 y 4 window.To access statistical media distributions: distr 2nd vars Example: if you want the probability that a sample from the standard normal distribution will be between z -0.3 and.5, press distr 2 -0.3,.5 ) enter Note the commas.When the graph is traced, the x -coordinate of the Trace cursor equals an integral multiple.1.TI-84 Plus C Graphing Calculator Important Keystrokes.The TI-84 Plus C graphing calculator offers some very advanced functions, but to get to those advanced features, you have to know the basic keys to press.
