Sb^ax (dx)
B^ax
___________
a log b



(All that is one equation, not 3)

Is this a real equation is it is just some unknown mathematics like the movie said?

Dx is real; can be taken as a derivative or differential.
Could be real if you took the top two as multiply and divided by the third.

Have you watched Colossus Forbid project? If yeah, what math equations appeared there that is unknown to man? Did the makers of the movie just put a bunch of letters and numbers all mixed up :D??

I saw in in 1970 when it was released on TV. That's nearly 39 years ago. You expect me to remember?

BTW: It's Colossus: The Forbin Project , not Forbid

This is a very good book:

The Adolescence of P-1 - Wikipedia, the free encyclopedia (http://en.wikipedia.org/wiki/The_Adolescence_of_P-1)

This is in book and movie form. Saw both.

Demon Seed - Wikipedia, the free encyclopedia (http://en.wikipedia.org/wiki/Demon_Seed)

Usually in movies like this they simply string a bunch of math symbols together to make it look intricate. They'll often use integrals and summation signs because they look especially "mathy."

I'm having a hard time trying to decipher what the equaton is that you tried to write - is it like this?


\int b^{ax} dx \\
B^{ax} \\
------ \\
a \ ln(b)

If that is what they're getting at, take note that

\int b^{ax}dx=\frac{b^{ax}}{aln(b)}

which looks very near to what they have, except for the capital B.

Excellent insight, Galactus! (I Itried to give you a greenie but I'm not allowed.)

Those who make movies know that most people do not know much about more advanced math, so they can scribble 'mathy' looking symbols on some blackboard or what not and it looks impressive. Some shows do seek the advice of mathematicians so as to be accurate.
I believe the show NUMB3RS does that. I think they use mathematicians from the University of California as consultants.

No, there is no f looking thing at the beginning, the rest is correct though. (What is that called you know?)

The f looking thing... haha

That 'f symbol' is the symbol for integration. It's a calculus thing.

I bet there is some sort of relationship, though, with that formula and the integral of an exponential function. I, and others, thought that S you used may have been a way of writing the integral sign.

It's an integral symbol.

if say f(x) = 2X^2+2, then dy/dx = 2X

The indefinate integral of dy (integral symbol) = 2X dx

is 2X^2+c where c is an arbitrary constant

You have to put limits on the integral to be able to find the original function.

dy/dx is called the derivativeof y with respect to x and is essentially the slope of a function at any point in time.

So if you think about it, if you know the slope at all points. Think of a straight line for the time being, the only thing that sets one line apart from another is it's intercept, but they are all parallel.

The indefinate integral is esentially the curve with a zero offset.

The Calculus branch of mathematics.

:D I feel like an alien trying to signal to human civilization :D

You'll get to learning about integrals and the other stuff that KISS talked about when you study the calculus - perhaps when you are in 11th or 12th grade. The integral basically means the area under the curve of the function - in this case the area under the function
f(x) = b^{ax}

I just learned this:

y= mx + b

Anyone remember what that was??

Slope intercept form of a line equation.

y=mx+b

m is the slope of the line and b is where it crosses the y-axis(y intercept).

That is why it is called the 'slope intercept' form'.

Suppose we want the equation of the line that passes through (1,3) and (-5,8).

The slope is just rise over run. In other words, the difference in the y values divided by the difference in the x values.

m=\frac{8-3}{-5-1}=\frac{-5}{6}

That means the line goes down 5 units for every 6 units it goes horizontally.

Plug either one of the sets of data points in for y and x and solve for b to find where it crosses the y axis.

3=\frac{-5}{6}(1)+b

b=\frac{23}{6}

The line equation is y=\frac{-5}{6}x+\frac{23}{6}

There ya' go.

Yup, learned that last night while sneaking around my room at 12 a.m :D
My room creaks so much so I have to be careful :rolleyes:

About to read the Graphing Inequalities section... maybe tonight I'll stay up till 1 ;)

Wow, you really are a maniac! :)

Haha
