Before performing a calculation for the first time, you should use the set up screen to specify the angle unit and display format. k kkkkkSetting the Angle Unit (Angle) 1. Display the set up screen and use the f and c keys to highlight “Angle”. 2. Press the function key for the angle unit you want to specify. •{Deg}/{Rad}/{Gra} ... {degrees}/{radians}/{grads} 3. Press J to return to the screen that was on the display when you started the procedure. • The relationship between degrees, grads, and radians is shown below. 360° = 2p radians = 400 grads 90° = p/2 radians = 100 grads k kkkkkSetting the Display Format (Display) 1. Display the set up screen and use the f and c keys to highlight “Display”. 2. Press the function key for the item you want to set. •{Fix}/{Sci}/{Norm}/{Eng} ... {fixed number of decimal places specification}/ {number of significant digits specification}/{exponential format display range toggle}/{Engineering Mode} 3. Press J to return to the screen that was on the display when you started the procedure. u uuuuu To specify the number of decimal places (Fix) Example To specify two decimal places 1(Fix) 3(2) Press the function key that corresponds to the number of decimal places you want to specify (n = 0 to 9). • Displayed values are rounded off to the number of decimal places you specify. Before Starting Calculations... 1 - 1 u uuuuu To specify the number of significant digits (Sci) Example To specify three significant digits 2(Sci) 4(3) Press the function key that corresponds to the number of significant digits you want to specify (n = 0 to 9). • Displayed values are rounded off to the number of significant digits you specify. • Specifying 0 makes the number of significant digits 10. u uuuuu To specify the exponential display range (Norm 1/Norm 2) Press 3(Norm) to switch between Norm 1 and Norm 2. Norm 1: 10–2 (0.01)>|x|, |x| >1010 Norm 2: 10–9 (0.000000001)>|x|, |x| >1010 u uuuuu To specify the engineering notation display (Eng) Press 4(Eng) to switch between engineering notation and standard notation. The indicator “/E” is on the display while engineering notation is in effect. The following are the 11 engineering notation symbols used by this calculator. Symbol Meaning Unit Symbol Meaning Unit E Exa 1018 m milli 10–3 P Peta 1015 m micro 10–6 T Tera 1012 n nano 10–9 G Giga 109 p pico 10–12 M Mega 106 f femto 10–15 k kilo 103 • The engineering symbol that makes the mantissa a value from 1 to 1000 is automatically selected by the calculator when engineering notation is in effect. 1 - 1 1 - 1 Before Starting Calculations... k kkkkkInputting Calculations When you are ready to input a calculation, first press A to clear the display. Next, input your calculation formulas exactly as they are written, from left to right, and press wto obtain the result. Example 1 2 + 3 – 4 + 10 = Ac+d-e+baw Example 2 2(5 + 4) . (23 . 5) = Ac(f+e)/ (cd*f)w k kkkkkCalculation Priority Sequence This calculator employs true algebraic logic to calculate the parts of a formula in the following order: 1 Coordinate transformation Pol (x, y), Rec (r, q) Differentials, quadratic differentials, integrations, S calculations d/dx, d2/dx2, odx, S, Mat, Solve, FMin, FMax, ListO Mat, Fill, Seq, SortA, SortD, Min, Max, Median, Mean, Augment, MatO List, List ALGBR Mode unique commands expand(, factor(, tExpand(, tCollect(, o(, diff(, solve(, tanLine(, collect(, combine(, sequence(, sumSeq(, expToTrig(, trigToExp(, signum( 2 Type A functions With these functions, the value is entered and then the function key is pressed. x2, x–1, x !, ° ’ ”, ENG symbols 3 Power/root ^(xy), x 4 Fractions ab/c 5 Abbreviated multiplication format in front of p, memory name, or variable name. 2p, 5A, X min, F Start, etc. 6 Type B functions With these functions, the function key is pressed and then the value is entered. , 3 , log, In, ex, 10x, sin, cos, tan, sin–1, cos–1, tan–1, sinh, cosh, tanh, sinh–1, cosh–1, tanh–1, (–), d, h, b, o, Neg, Not, Det, Trn, Dim, Identity, Sum, Prod, Cuml, Percent, AList 7 Abbreviated multiplication format in front of Type B functions 3, A log2, etc. 8 Permutation, combination nPr, nCr 9 . , / (.) 0 +, – 2 Before Starting Calculations... 1 - 1 ! Relational operator =, G, >, <, ., . @ And, and # Or, or, xor, xnor • Execution is normally performed from left to right, except in the following cases when it is performed from right to left. ·When functions with the same priority are used in series: exIn 120® ex{In( 120)} ·When power calculations are used in series in the ALGBR Mode: [5^3^2 ® 5^(3^2)] ·To produce the same result in the RUN Mode, the above calculation should be input: (5^3)^2 • Compound functions are executed from right to left. • Anything contained within parentheses receives highest priority. Example 2 + 3 . (log sin2p2 + 6.8) = 22.07101691 (angle unit = Rad) 123456 k kkkkkMultiplication Operations without a Multiplication Sign You can omit the multiplication sign (.) in any of the following operations.
