Appendix Store VctA = (1, 2) and VctC = (2, -1, 2). Copy VctA = (1, 2) to VctB and then edit Vector B to VctB = (3, 4). • The following examples use the vectors input in Examples and (VctA, VctB, VctC). VctA + VctB (Vector Addition) 3 × VctA (Vector Scalar Multiplication) VctB - 3 × VctA (Calculation example using VctAns) VctA • VctB (Vector Dot Product) VctA × VctB (Vector Cross Product) Obtain the absolute values of VctC. 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. *1 cos θ = (A•B) , which becomes θ = cos-1 (A•B) AB AB *2 Size 1 vector perpendicular to both A and B = (A × 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: finestructure 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
