  1. TI 83/84 Calculator Training Session 1 -- Part 1 – Calculator Basics Order of Operations • Calculations within parentheses are evaluated first • Priority Order Level • Functions that precede the argument, such as sin(, log(, or ( • Functions that are entered after the argument, such as 2, -1, !, o, r, and conversions • Powers and roots such as 2^5 or 5x • Permutations (nPr) and Combinations(nCr) • Multiplication, Implied multiplication, and division • Addition and Subtraction • Relational functions, such as > or < • Logical operator and • Logical operators or or xor • Within a priority level, functions are evaluated left to right

ZStandard Xmin = -10 Xmax = 10 Xscl = 1 Center: Origin ZDecimal Xmin = -4.7 Xmax = 4.7 Xscl = 1 Center: Origin When tracing, x moves in tenths (0.1) ZInteger(After ZStandard or ZDecimal) Xmin = -47 Xmax = 47 Xscl = 10 When tracing, x moves in whole steps (1) ZInteger(After window centered at point (a,b)) Xmin = a – 47 Xmax = a + 47 Xscl = 10 Center: Cursor When tracing, x moves in whole steps (1) Zoom In / Zoom out Center: Cursor Zoom by factor of 4 (Source: TI 83/84 How to Cards 37 and 38 Summary of ZOOM Settings • Ymin = -10 • Ymax = 10 • Yscl = 1 • Replot: Immediate • Ymin = -3.1 • Ymax = 3.1 • Yscl = 1 • Replot: Immediate • Ymin = -31 • Ymax = 31 • Yscl = 10 • Ymin = b – 31 • Ymax = b + 31 • Yscl = 10 • Replot: <ENTER> • Replot: <ENTER> • ZTrig • Xmin = -(47/24)p • (or -352.5o) • Xmax = (47/24)p • (or 352.5o) • Xscl = p2 • (or 90o) • Center: Origin • ZFit • Xmin = unchanged • Xmax = unchanged • Xscl = unchanged • Allows you to see y values for all of the x’s in the domain of the graph • ZSquare • Adjusts the size of the window so that the x dimension and the y dimension are proportionate (e.g. a circle looks like a circle • Center of the graph is unchanged • ZBox • Allows you to frame the area of the graph you want to ZOOM in on • Use cursor (<ENTER>) to set opposite corners • Ymin = -4 • Ymax = 4 • Yscl = 1 • Replot: Immediate • Ymin = min(Yn) for Xmin < X < Xmax • Ymax = = min(Yn) for Xmin < X < Xmax • Yscl = unchanged
