I'm a college freshman and looking for some REUs that I would have a decent chance to get accepted into. I know it is really hard to get accepted as a freshman but I was wondering if anyone here knew anything or had any suggestions. I'm looking for astrophysics or particle physics mainly but I...

I'm doing fine with it. Calc 3 is before Linear Algebra.

I am currently in BC Calculus. Next year, assuming I do well on my AP tests and placement exams, I will be able to go into Linear Algebra. I plan to major, or at least minor, in mathematics. The school I am going to will not require me to take Calculus 3 next year since I have BC and will be...

But do you think a double major in astrophysics would help my chances of getting into a good program/research or do you think it won't make much difference? I would be happy doing research in astronomy related fields also, but I prefer math.

I am a senior in high school this year and am thinking about majoring in pure mathematics. If I do, what types of jobs would I be able to get with a BS or MS? If I do go pure math, is it better to get a teaching degree or to double major (if I do it would most likely be astrophysics related). I...

I was looking at the Gamma Function. I understood it a little bit, but in general it was way over my head.

I managed to get it by using substitution and then parts. Try making u=1/(1+x^2) and then when you get du, use u=1/(1+x^2) to solve for x to replace x with u. After that, use parts. Hope that helps I can give a more detailed answer if you still are having trouble.

My calc teacher taught us LIPET. Log, inverse trig, polynomial, exponential, trig. She says it always works and I've never found a problem where it doesn't. You pick u in the order of LIPET, and whatever remains is dv.

I was looking up how to find the derivative of a factorial and found this thread: https://www.physicsforums.com/showthread.php?t=1328 What is a discrete-space derivative? I tried looking it up, but had no luck. If someone could explain it in a way someone in calc 2 could understand that...

Thanks.

Now that I reread it I see it said probability amplitudes can be positive, negative, or complex numbers. What exactly is that? Every explanation I find involves complex math (since I'm not taking Calc 1 until next year almost all math is complex to me).

I'm currently reading "The Black Hole War" by Leonard Susskind. I'm the book the author says that when predicting probability in quantum you can have positive, negative, or complex numbers. How is this possible? The book literally says, "Do not try to understand this. Just accept it." I asked...
