Hi;

It is more useful to define it 0^0 = 1. The argument for this began with Euler who first said it. Here are a couple of more mathematicians:

From Concrete Mathematics p.162 (R. Graham, D. Knuth, O. Patashnik):

Some textbooks leave the quantity 0^0 undefined, because the functions 0^x and x^0 have different limiting values when x decreases to 0. But this is a mistake. We must define x^0=1 for all x , if the binomial theorem is to be valid when x=0 , y=0 , and/or x=-y . The theorem is too important to be arbitrarily restricted! By contrast, the function 0^x is quite unimportant.

Hi guys,

We added some cool new functions:

1) We added the ability to do summations (as suggested by anonimnystefy). For example, to do the sum

you would do the command: poly_x[evalsum{x^2*y+z,x,1,14}] . The result of the summation will be in terms of and

2) We added the ability to solve equations. This equation solving function is an exact solver. For example, to solve the equatoin where is the unknown, you would use the command poly_x[eqsolve(x^2+a*x+(b-3*c),x)]. Our solver will return the answer as and which are exact.

To do list:
1) Multiprecision (suggested by bobbym)
2) Coefficients (suggested by anonimnystefy)
3) Plotting for all variables (suggested by anonimnystefy）
4) Error message change (suggested by anonimnystefy)

Thanks again!

Hi;

Very nice capability. How did you get MathJax integrated into your page?

gauss_infinity · 2012-11-02 16:08:55

hi bobbym,

we just followed the instructions on their webpage...

Thanks for trying our website!!!

Hi;

You are welcome.

Okay, thanks. I will look at their site.

Shivamcoder3013 · 2012-11-02 23:46:12

Amazing online calculator.

gauss_infinity · 2012-11-03 05:48:40

Hi Shivamcoder3013,

Thanks for trying!

No problem. It is the first online advanced calculator that I plan on being attune using that (other then when I have access to my 89 titanium or nspire).

gauss_infinity · 2012-11-03 12:12:02

Yup! We will be adding more features so stay tuned!

We also try to keep usage as intuitive as possible. Much of the usage patterns are actually very similar to TI-89 or softwares like MATLAB, Mathematica, Maple. The nesting of operations and command interpretation is the same, so hopefully you get used to it fast! Moreover, some heavy operations not possible on graphing calculators will be possible on this platform due to more processing power available.

0^0=1? Is this a glitch?

gauss_infinity · 2012-11-03 12:14:11

No it is not a glitch. 0^0 is indeterminate, but for most purposes any to the power of 0 is defined to be 1 so that is what we adopted as well.

Shivamcoder3013 · 2012-11-03 12:15:25

Ah. Can you solve for x with it? Also, perhaps you should add a graphical interface. By the way, if you need some help coding it, feel free to ask.

gauss_infinity · 2012-11-03 12:16:37

what do you mean solve for

with it? btw thanks again.

anonimnystefy · 2012-11-03 12:17:26

Limits and random numbers would be nice to have as well...

Shivamcoder3013 · 2012-11-03 12:18:02

I meant a CAS interface. Lets say you type x+2=3. Solve for x.

gauss_infinity · 2012-11-03 12:18:09

and yup definitely, if we need help with coding we will definitely look around here

gauss_infinity · 2012-11-03 12:19:55

yes...just do poly_x[eqsolve(x+2-3,x)]

bobbym · 2012-11-03 12:20:36

I think you should stick with 0^0 =1 . Four mathematicians and Euler define it that way.

Shivamcoder3013 · 2012-11-03 12:20:41

Sure. I am quite proficient in PHP and JS, so I might be able to help. Also, I have coded a few online calcs myself.

gauss_infinity · 2012-11-03 12:21:29

hi anonimnystefy,

yea we will put that on our list as well....

thanks!

gauss_infinity · 2012-11-03 12:22:35

hi bobbym,

yea, we were about to hardcode it to indeterminate, but then realize most books actually use 1 for it haha so that is what we default to...

Shivamcoder3013 · 2012-11-03 12:23:43

And yes, you should add limits.

anonimnystefy · 2012-11-03 12:24:35

You are welcome. And thank you for putting your effort into this. I am sure it will be astonishing.

bobbym · 2012-11-03 12:25:46

Without it defined like that the binomial theorem would have problems.

Shivamcoder3013 · 2012-11-03 12:27:02

Which 4 mathematicians?
