What is the use of plot(x, y, ':') while plotting the graph?

x=0:pi/100:2*pi;

y=cos(x);

y2=sinx

plo(x,y2, ':')

why is ':' required?

[Rik]

The use of a colon like this implies plot is a variable. Otherwise this is a syntax error.

But plot(x,y2) also shows the results.

[Rik]

Did you perhaps mean plot(x,y2,':')?

If so, read the documentation for the plot function. It will clearly explain what that does.

':' is dotted line joining the points.
