Hey guys I need to know a simple answer to an exciting problem
I need to find as to how many 2n digit numbers exist such as sum of first n digits is equal to sum of second n digits
where a number with leading zeros is absolutely fine
E.g. for n = 8

There is a straight line which keep getting new "ends" and creating new segments.  First, it has 2 then 3 ends,4, 5 6 etc.  As you advance adding new ends, the number of segments icreases in a larger number than the number of ends. The first 2 is only 1 segment, when it's 3 is 3 ...

i  have three question that i need help with.
your input would be really appreciated :)
1) What properties of the curve remain unchanged when you
reparametrize the curve?

I'll just state it first:
f(z) is analytic
integral, over simple closed curve C that incloses z0, of:  f(z) / (z
- z0) = 2*pi*f(z0)

I will be willing to trade for the following:

I am looking for a free online graphing application I can use to teach high
school math. I have a TI-83 Plus, which I like, but I am looking for an
online app with a bigger screen area and better resolution. (I can project
my laptop display onto a screen for the class.) Right now ...

Anybody have solution manul for "Advanced Engineering Dynamics 2nd
Edition" by Jerry H. Ginsberg?

Thanks in advance for anybody replying.

I really, really need the solutions to ALL problems from Calculus
Early Transcendentals 6th Ed. by James Stewart.
Thanks!!

I'm trying to prove:
"Let x >=0 be a real number such that for any eps > 0, x <= eps. Show that x = 0."
Here's my attempt:
Since x <= eps, this implies x - eps <=0. Since eps can be chosen as small as we like, it follows x = 0.

I really need the solution manual for the 'Elementary principles of
chemical processes

GraphEasyRect was previously available as an applet. Now we have
converted it to a desktop standalone application that runs on multiple
platforms Windows, Mac, and Linux
This tool allows graphing functions in cartesian plane, points of

Y= X^2 -3X -4
Swap sides of the equation to put X on left.
     2          
   (X -3X-4) = Y
