# 3D Distance Formula Calculator Program

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.

The distanct from $(x_0, y_0, z_0)$ to $(x_1, y_1, z_1)$ is
$$\sqrt{(x_1- x_0)^2+ (y_1- y_0)^2+ (z_1- z_0)^2}$$
