This guy did a very nice job of collecting many astronomy videos (I am unsure if it is copyright infringement). The link is http://www.youtube.com/user/NGC6822
Ethanol seems to be popular for an alternative fuel for cars. If you distilled the ethanol by cooling it and exceeding the saturation point, because it has a lower density than water (.789 grams/cubic cm), the ethanol it would float to the top. You could take the mixture below the freezing...
I see people say they get 5's on their AP classes their senior year. The exam for the class is at the end of the year and you apply for college in the fall. How do colleges know what you take your senior year and what you got, if the school year isn't over. Do they just ignore the last...
I realize there is an easy algebraic equation for the remainder of the linear congruence, but for the quadratic congruence I don't recognize any pattern other than the standard 2n-1 from the series for calculating the square of a number.
I'm working on some basic number theory. I came across an idea and I'm having trouble finding a general solution.
A == X mod (L-k)
k^2 == Y mod (L-k)
It is the equivalent of:
( k^2 - A ) / ( L - k ) = integer
A and L are two different pre-chosen numbers. I know L-k is a prime number...
I've been looking into the Python.
The python.org interpreter didn't work but I do have a command line interpreter.
How to you run a script file from the command prompt?
I've tried "read" and "write" functions but I'm pretty sure those aren't the right ones to use.
Also, I can't figure...
I want to get into programming. Does anyone have any suggestions for books for beginners?
My goal is to make a program to finish my project at https://www.physicsforums.com/showthread.php?t=172789
Is there already a program that can do this?
Is there a quick way to find integer values of x that give integer values for y?
(x^2-R)/(P-2x)=y
sqrt(R) rounded down<x<P/2
an equivalent equation is
x^2+Px+R=y y= a perfect square
sqrt(x^2+Px+R)= integer
P and R are integer values. They are very large...
Thanks for pointing that out to me. I guess I'll choose a different counselor today because that recommendation proved even more to me that my previous counselor is incompetent. Thanks again, I could have wasted a whole year of math.
I'm thankful for the help people have given me.
The books that have been recommended are pretty expensive. My mom says she can pay for them because their for my education. But, a friend offered to lend me a book titled Advanced Calculus A Course in Mathematical Analysis by Patrick Fitzpatrick...
I have several questions hoping someone could help me.
I am nearing the end of my 10th grade year. I realized I should start thinking about college soon so I taughted myself calculus from Howard Anton's book called Calculus with Analytic Geometry last month hoping I could test out of...
