It seems like you need a course on the fundamentals of programming!
What output did you get?
How does it differ from what you want?
You define 2 functions but never call them. So they will never run.
Do you know the difference?
I will not write a program for you, but will, as offered, help.
For starters what do the colons in the input mean? Are they decimal
points? When I apply the input xmin = 2:5, dx = 0:5 and nx = 11 to the
series definition xmin, xmin+dx I get 2.5 3.0 3.5 etc to infinity. Where
did the -2.5 in the output come from?
If you assume xmin = -2.5 then it will work.
How in Python can you express this series (for loop?)
What class is this question from? Have you met the prerequisites for the
class? If so why is the instructor expecting you to do something he has
not prepared you for?

I have tried to do the program. But I still cant get the output desired. Could
you please give me a hint if I am close to whats required?
Thank you for your time once again. I am sure you have more complex programs to
deal to.

dx?")c=raw_input("what is the value of nx?")
