Neurocomputing: An Introduction, present chapter, we will be concerned primarily with the measurement of distances and angles on surfaces. We will see how such . properties of surfaces can be expressed in terms of certain fundamental quantities called the metric coefficients. The theory discussed here and in Chapter 13 was invente
