what is the difference between 2 script mentioned below for the above question?
Script 1: Script 2:
x=linspace(0,pi,100); x=[0:pi];
>> y=cos(x); y=cos(x);
>> z=1-((x.^2)/2)+((x.^4)/24); z=1-((x.^2)/2)+((x^4)/24);
plot(x,y,x,z) plot(x,y,x,z)

Looking again, I see that you only have one call to plot. You do not need hold on with the way you plot.

As edward pointed out, in script 2 you are missing . before ^4 . That would cause the code to fail.
If that were to be changed, then both scripts would work. However, the first script would plot 100 points starting at 0 and ending at pi, but the second script would plot only at locations [0, 1, 2, 3]

Short answer: script 1.
x = linspace(0,pi,100)
creates a vector with 100 values in between 0 and pi, so when plotting y and z against x you get a nice smooth plot.
x = 0:pi
on the other hand creates just a vector of length 4. [1 2 3 4] Plotting y and z over this will not be smooth.
Also in script 2 there is a missing '.' before '^4'
