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.

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
