• If you want to create another vector, repeat this procedure from step (1). Copying the Contents of One Vector to Another Vector You can copy the contents of Vector Answer Memory (VctAns) or of a vector in vector memory to another vector in vector memory. The vector copy operation is basically the same as the matrix copy operation. See “Copying the Contents of One Matrix to Another Matrix” for more information. k Performing Vector Calculations To perform a vector calculation, display the vector calculation screen by pressing the A key. Vector Answer Memory Screen The Vector Answer Memory screen shows the result of the last vector calculation. VCT Stands for “VctAns”. •You cannot edit the contents of a cell. •To switch to the vector calculation screen, press A. k Vector Menu Items The following are the menu items on the vector menu that appears when you press 15(VECTOR). Select this menu item: When you want to do this: 1Dim Select a vector (VctA, VctB, VctC) and specify its dimension 2Data Select a vector (VctA, VctB, VctC) and display its data on the vector editor screen 3VctA Input “VctA” 4VctB Input “VctB” 5VctC Input “VctC” 6VctAns Input “VctAns” 7Dot Input the “ • ” command for obtaining the dot product of a vector E-63 Appendix <#106> Store VctA = (1, 2) and VctC = (2, –1, 2). <#107> Copy VctA = (1, 2) to VctB and then edit Vector B to VctB = (3, 4). • The following examples use the vectors input in Examples <#106> and <#107> (VctA, VctB, VctC). <#108> VctA + VctB (Vector Addition) <#109> 3 . VctA (Vector Scalar Multiplication) VctB – 3 . VctA (Calculation example using VctAns) <#110> VctA • VctB (Vector Dot Product) <#111> VctA . VctB (Vector Cross Product) <#112> Obtain the absolute values of VctC. <#113> Determine the size of the angle (angle unit: Deg) formed by vectors A = (–1, 0, 1) and B = (1, 2, 0), and one of the size 1 vectors perpendicular to both A and B. (A•B) (A•B) *1 cos .= , which becomes .= cos–1 .A..B..A..B. (A . B) *2 Size 1 vector perpendicular to both A and B = .A . B. Scientific Constants Your calculator comes with 40 built-in constants that are commonly used in scientific calculations. You can use the scientific constants in any calculation mode except for BASE-N. •To recall a scientific constant, press 17(CONST). This displays the scientific constant menu. Input the two-digit number that corresponds to the constant you want to recall. When you recall a constant, its unique symbol appears on the display. • The following are all of the built-in scientific constants. 01: proton mass; 02: neutron mass; 03: electron mass; 04: muon mass; 05: Bohr radius; 06: Planck constant; 07: nuclear magneton; 08: Bohr magneton; 09: Planck constant, rationalized; 10: fine- structure constant; 11: classical electron radius; 12: Compton wavelength; 13: proton gyromagnetic ratio; 14: proton Compton wavelength; 15: neutron Compton wavelength; 16: Rydberg constant; 17: atomic mass unit; 18: proton magnetic moment; 19: electron magnetic moment; 20: neutron magnetic moment; 21: muon magnetic moment; 22: Faraday constant; 23: elementary charge; 24: Avogadro constant; 25: Boltzmann constant; 26: molar volume of ideal gas; 27: molar gas constant; 28: speed of light in vacuum; 29: first radiation constant; 30: second radiation constant; 31: Stefan-Boltzmann constant; 32: electric constant; 33: magnetic constant; 34: magnetic flux quantum; 35: standard acceleration of gravity; 36: conductance quantum; 37: characteristic impedance of vacuum; 38: Celsius temperature; 39: Newtonian constant of gravitation; 40: standard atmosphere E-64 •The values are based on ISO Standards (1992) and CODATA Recommended Values (1998). For details, see Appendix <#114>. Appendix <#115> and <#116> Perform all of these examples in the COMP Mode (N1). Metric Conversion The calculator’s built-in metric conversion commands make it simple to convert values from one unit to another. You can use the metric conversion commands in any calculation mode except for BASE-N and TABLE. To recall a metric conversion command, press 18(CONV). This displays the metric conversion command menu. Input the two-digit number that corresponds to the metric conversion you want to recall. See Appendix <#117> for a list of all of the metric conversion commands and conversion formulas. •Conversion formula data is based on the “NIST Special Publication 811 (1995)”. * “cal” uses the NIST value at 15°C. Appendix <#118> to <#120> Perform all of these examples in the COMP Mode (N1). Technical Information k Calculation Priority Sequence The calculator performs calculations according to a calculation priority sequence. • Basically, calculations are performed from left to right. •Expressions within parentheses have the highest priority. • The following shows the priority sequence for each individual command. 1. Function with parentheses: Pol(, Rec( .(, d/dx(, .( P(, Q(, R( sin(, cos(, tan(, sin–1(, cos–1(, tan–1(, sinh(, cosh(, tanh(, sinh–1(, cosh–1(, tanh–1( log(, ln...
