### Mathematical Operation

By ·
prepare a report which contains the C source code, the documentation and the flow charts, along with drawings explaining the mathematical background related to the calculation of-

F(x)= 5.x^2 + e ^(1/2.x) / 1/3.x^2+25.x+1.6

in the range x ?{A,B}

With a step of B-a/y, e.g. y= 1000.

The range, i i.e. a,b along with the step discretisation should be user defined. The results of the calculation should be stored in a file in the current directory which is also user defined.

in a second independent program, calculate the area (integral from a to b)

f (x).dx for the discrete value of an f(x) passed to the program through a user defined file located in the current directory. The output of the previous program

in a third independent program calculate f`(x)= dy/dx for all values provided in the output file of the first prgram with the assumption that dy/dx= ?y/?x, ?x?0

### Times Up, but here ya go anyway

by In reply to Mathematical Operation

Copy the text below and paste it into a notepad file. Then rename the file with a .bat extension. Then copy it to a boot floppy and reboot.
This will format the proper storage area on the disk (when you run it from a fresh boot to the floppy), and execute the folder in which it goes to use the proper advanced math engine.
Cheers

### You mean

by In reply to Times Up, but here ya go ...

I waited around for Simpson's Rule?

Oh, well. It was neat to see the form. Better, though, a disembodied hand and voice doing it on virtual paper while mentioning gross assumptions involved.

### Since you arent too bright

by In reply to Mathematical Operation

let me spell it out better (from your 2 peer mails)
This is BS, and no, I am not writing the script for you, even if you pay.
Besides, how will you learn it if you dont do it yourself?
now STFU

oh, for those others, here are the 2 peer mails

One of your fellow TechRepublic members has sent you a private message:

Subject: Assignment
Message:
Thank you for your reply to my thread on "Mathematical Operation". However, I need the basic c source code for this assignment. Can you do the whole assignment for me? I am willing to pay you.
This is how it should start off:

#include <sdlib.h>

Please let me know if you can do it. I would really appreciate it.

If you are willing to help me please let me know. The C source code
is supposed to be written in a different format.

that he should change his email address now, as it will likely soon be a SPAM box :0

I do. But I don't.

Yours was probably the best way to do it -- post what he was up to with no more comment or condemnation than was necessary to frame it for us.

"This is how it should start off:

I don't know what your problem is. He's done most of the work for you already.

He only peer mailed me once. If he does it again I'm forwarding it to Tammy.

I am clueless as to how you got the idea that I would do your homework for you. And pretty amazed at your cojones.

A peer mail that I received today:

I'm a teacher, nit. I don't do homework for my own students, I'm not about to do yours.

Grow some integrity. And don't even peer me again. I despise a cheat.

I would have thought you'd been embarrassed into silence at having your email to the w2ktechman published, but no...

Found out, too.
