    r-hat cross phi-hat = theta-hat

    r-hat is the unit vector in a direction in which only r changes and theta and phi remain constant

    phi-hat is the unit vector in a direction in which only phi changes and theta and r remain constant, and

    theta-hat is the unit vector in a direction in which only theta changes and r and phi remain constant.
