Not carry the solutions completely into the graphical realm. Kennelly in 1914 simplified the mathematical evaluation of problems relating to guided wave propagation in that period, but did Tables of hyperbolic functions published by A. Hence these physical phenomena lend themselves quite naturally to graphical representation. The laws governing the propagation of electromagnetic waves along transmission lines are basically simple however, their mathematical representation and application involves hyperbolic and exponential functions (see Appendix A) which are not readily evaluated without the aid of charts or tables. 1.1, provides an interesting example of a chart which was used by mariners and astronomers for over 20 centuries, even though the mathematics was well understood. The ancient astrolabe, a Renaissance version of which is shown in Fig. For example, a simple physical relationship such as that expressed by Ohm's law does not require a graphical representation for its comprehension or use, whereas laws of spherical geometry which must be applied in solving navigational problems may be sufficiently complicated to justify the use of charts for their more rapid evaluation. Usually the more complex the law the more useful is its graphical representation. The physical laws governing natural phenomena can generally be represented either mathematically or graphically.
