3D Distance Formula Calculator Program

  1. Nov 19, 2011 #1
    Hello. I have the distance formula programmed into my calculator and I searched for a distance formula that includes the z-axis but I couldn't find any. Does anyone know how to make such a program for the TI-84?

    Thank you.

    It's just the obvious extension of the two dimensional formula:
    The distanct from [itex](x_0, y_0, z_0)[/itex] to [itex](x_1, y_1, z_1)[/itex] is
    [tex]\sqrt{(x_1- x_0)^2+ (y_1- y_0)^2+ (z_1- z_0)^2}[/tex]
