Boltzmann amongst others end up tragically compared to Islamic mathematicians such as Al-Kindi, Al Jabir al Hayyan, Al-Khwarizmi and others? Is it because the reliazation that there is denial that God exist creates more doubts and therefore mental breakdown?

Let P be a point on the curve y=x^3 and suppose the tangent line at P intersects the curve again at Q. Show that the slope at Q is 4 times the slope at P.

I'm kinda lost on this..
Thanks!

I saw a documentary about how passionate this mathematicians and how they use mathematics to describe abstract things like, truth, existence, thinking, God, nature, and most of all philosophy. I don't really get it.

A king has some (finite) number of subjects. One day he lines them all up in a row, facing towards the front of the row. He goes from the front of the row to the back, giving each subject a hat - either red or blue.

No subject can see his/her own hat, nor can any subject see behind himself/herself. But a subject can see ALL of the others that come before him/her in line.

So the king has made his way to the back of the line, and now he will ask the person at the back of the line "What color is your hat?" while brandishing a big sword. If answered correctly, the person is freed. If answered incorrectly, the person is beheaded immediately. No communication between subjects is allowed, although they can hear each others' guesses.

You have a chance to meet with the subjects ahead of time - the night before this incident - to give them a strategy that will save the most number of lives (guaranteed, not a probability or expected outcome). The strategy that saves the most will be chosen.

(x)=-x^3-x^2+2x-8 find f(-1),f(0),f(2)

f(-1)=(-1)63-(-1)^2+2(-1)-8
-3-2+-2-8
answer -15

f(0)^3-(0)^2+2(0)-8
0-0+0-8
answer -8

f(2)^3-(2)^2+2(2)-8
8-4+4-8
answer is 0

Okay, here's the equation:

log(base 2)(24) - log(base 2)(3) = log(base 5)(x).

We're solving for x here. I get that you use the quotient rule.

Then you get:
log(base 2)(24/3) = log(base 5)(x)
log(base 2)(8) = log(base 5)(x)

But what do you do after that point and WHY do you do it (i.e. what rules say to do it that way)? THANK YOU SO MUCH!!! I'll pick a best answer TODAY!

Say one was given the following complex number in cartesian form, (2)-(2isqrt3) » a - bi. And one was told to transform it into polar form » rcis (theta).
Would one take the degree as 150, or -60. taking 150, will give the answer 4cis(5/6pi) and taking 60 will give 4cis(-1/3pi).

So which degree should one take, and why so?
