# Request: Adder Naga teaches Mathsby hippo2

This picture is for

He wished for an Adder Naga. In his own Sleeping Stories Universe (SSU), Adder Nagas are an intelligent race of Nagas who have great interest in maths and teach maths to other inhabitants of SSU. fav.me/d4qgjxv

This Adder Naga seems to teach some calculus, but also stochastics is possible, since the function f(x) describes the Gaussian Distribution.

The Gaussian Distribution is important to describe e.g the body height of a population. Imagine you are designing a car and you have to make the roof of the car heigh enough so most people fit in. But how to find the best height?

If you calculate the x-value of the maximum, you find the average body height of the population.

If you calculate also the second derivation of f(x) and determine the position of the two inflection points, you have calculated the range of the standard deviation of the Gaussian Distribution. The value of the integral between the two inflection points is about 0,683. Since the complete area under the graph is exactly 1, the standard deviation covers 68,3% of the complete area.

This also means, that the x-values of the two in inflection points mark the body heights, between which you will find 68,3% of the population.
Two times the standard deviation cover around 95% of the population.
Three times the stnadard deviation cover around 99% of the population.

Designers usually use two times the standard deviation when dertermining e.g. the height of a car.

Would you liek her to be Arithimia?

That's would be nice.

I learned this rule in statistics, but not the math behind it.

I only took Calc I. :I  No way I'm doing this.
Featured By Owner Dec 14, 2013
Yeah, we teach the connection between the statistics and the calculus only in advanced courses.

I'm not so familiar with the contents of Calculus courses. Did you learn how to do the derivation part and the integration part mentioned on the chalk board? (In other words: where these derivations and integrations part of Calculus I?)
Featured By Owner Dec 15, 2013
We learned how to take a derivative and how to integrate, but we only did really basic things.  An equation like this one is a no-no.
Featured By Owner Dec 17, 2013
I see, so you don't know chain and product rule of derivation?
Featured By Owner Dec 17, 2013
We covered those.  I imagine there's a ton more than what I learned, though.
Featured By Owner Dec 17, 2013
That's all you need to solve the first half of the problem on the blackboard. The integration how ever is a bit more difficult.
Featured By Owner Dec 17, 2013
I can see that..
Featured By Owner Sep 1, 2013
However, I don't really understand this level of math that she's doing.
Featured By Owner Sep 1, 2013
That is quite difficult stuff. Advanced Calculus on high school level or even university level.

I think she's a nice naga here.

Nicely done!  Thanks for drawing this!
Featured By Owner Aug 24, 2013
I'm glad you like it. I hope the maths isn't to frightening.
Featured By Owner Aug 24, 2013
I agree this is very cute we'll be calling math-loving nymphs arithmades. If you have any other math-loving race ideas please let us know!

Hey Nazor, I hope you have room for a huge @\$\$ arcade in your SSU, because Emporer made my dream arcade come true! It's a four leveled Arcade called "Joystick Paradise" and I was inspired by arcades from the 80's and the arcades I saw back in Japan!

Sure no problem. You should check out the bios for Toadettes and Hylians. Any other ideas for races or subraces please let us know
