I plotted two 2-D graphs (the range of values taken by the abscissa were the 
same->[0,0.03].. the functions are well-defined for x<0 also). Both graphs 
peaked at x=0 decaying quickly as x increased. Peak values: 300 and 400 units 
for the two.
 Using "Show" I tried to get a combined graph. What I got was the two graphs.. 
with the axes of one slightly shifted (horizontally) from the other's causing 
distortion in the numbers marked on the x and y-axis.
 I tried reproducing the example provided in the Mathematica book (Section 
1.9.3) that involves combining a Bessel and Neumann function (and that too with 
different ranges for x!!) and it worked! The section said that the axes are 
supposed to scale appropriately to accomodate both the functions. 
 Question is .. if Mathematica plotted the individual graphs correctly, what 
went wrong when I simply tried to get the two together?
 An associated problem (though I do have a guess at the answer).. One of the 
functions is such that when x is around 0.03, it is already tending to zero.I 
provided an initial plotting range of [0,0.08] for this function. "Plot" gave 
me a contracted plot with x going from 0 to 0.03 (approximately). Maybe the 
command is programmed to remove "tails" (that are considered redundant?) of 
decaying functions from their plots. .. T/F?
