Table H. Graphical addition. 

 One addend tabulated as function of the sum and the other addend. 



Fig. 66. Graphical addition of single-valued scalar fields. 

 (The fine lines represent the given fields, the thick 

 lines their sum.) 



Fig. 67. Graphical addition of multiple-valued scalar 

 fields (fields of angles). The fine lines represent 

 the given fields, the thick lines their sum. Observe 

 the consequences of the multiple- values: 32+32 

 = 64 = 0, 48+32 =80 = 16, etc. 



150. Multiplication of Scalar Fields. Let the function <p = f (a, /3) be 

 (a) <p = a 



In order to use the continuous method we solve with respect to /3 or a
