I honestly enjoy the smell like some people enjoy the smell of lemons. Last year at school I asked on of my teachers about it, and she said that it could actually be that I have a defect in my brain or my sense of smell that makes me enojy the 'stench' of a skunk.
I don't know if that's true though, because I also love the smell of lemons, oranges, bubble gum, etc.

Could someone explain why I like it? XD

Well this practice problem in my AP Calculus practice book has a strange problem giving me a hard time. It says:
"Each limit represents the derivate of some function f at some number a. State such an f and a in each case".

and the problem is...
lim h---> o of...
(1+h)^10 - 1
---------------- [divided by]
h

I tried using the definition of a derivative and also the alternate definition of a derivative [aka: derivative at a point] and I didn't quite get the answer from the answer key. So, how is this actually done?

Enhance this diagram to include a circle that is circumscribed about the outer most figure - that means it touches (or is as close as possible to) all the vertices.

Hi, I'm stuck on a question about square matrices for quite a long time. Any help would be greatly appreciated!

1. Let A and B be square matrices with the same size.
a) Give an example in which (A+B)^2 =/ (does not equal to) A^2 + 2AB + B^2
b) Fill in the blank to create a matrix identity that is valid for all choices of A and B. (A+B)^2 = A^2 + B^2 + _______.

2. Let A and B be square matrices with the same size.
a) Give an example in which (A+B)(A-B) =/ (does not equal to) A^2 - B^2
b) Fill in the blank to create a matrix identity that is valid for all choices of A and B. (A+B)(A-B) = ____________.

Thanks!

I am writing an informative 6-8 min speech on string theory. I am not going to get too in depth; just use basic analogies. I wanted to show the benifits of using strings to marry quantum physics and general relativity. All I was going to do is show that if the fundamental building blocks are particles then they would be like dice. I would then display some dice, rolling them, etc. Then I would say that quantum space is like many, many dice- probablity rules here, making things not so easy to predict. I heard on a documentary that the strings in string theory "calm" this quantum froth. So I was going to use rubber bands to show that the dice, instead of being treated as seperate entities, could be treated as sets of probabilty equations, which are interpretated as strings. It is easier to understand this quantum froth (the calming) by looking at it as a multitude a strings. By this slight "calming" of the equations, quantum physics and general relativity are married.

A model rocket is fired vertically from rest. It has a net acceleration of 17.5 m/s^2. After 1.5s, its fuel is exhausted and its only acceleration is that due to gravity. The rocket has a mass of 87g and you may assume the mass of the fuel to be much less than 87g. What was the net force on the rocket during the first 1.5 s after liftoff? What force was exerted on the rocket by the burning fuel? What was the net force on the rocket after its fuel was spent? The rocket's vertical velocity was zero instantaneously when it was at the top of its trajectory. What were the net force and acceleration on the rocket at this instant?
