Pro-tip on how to calculate eigenvalues with a TI 83 or 84 of matrix A with dimensions n x n: make a function: y = det([A] - X*identity(n)) and find the zeros of this function

Is 48 an even number? A friend and I have been discussing this question for a few hours now and can't seem to come to a resolution. Can you help us out?

I need to show using delta epsilon proof that the limit as x goes to 0 of 1/lnx is 0. Can anyone help?

Found this in an old notebook. Does anyone know what it means? It probably has something to do with microeconomics and if I had to guess I'd say there are growth-rates in there. Thanks for the help.

If two particles are quantum entangled and one falls into a black hole. What happens to the other? Also lets say we make a video camera whos hard drive is made up completely of atoms that are quantum entangled with an exact duplicate harddrive and we throw the video camera into a blackhole and the camera somehow survives and is spewed out in another dimension or time or place and still retains its shape somehow. Could we be able to download whats off the harddrive we kept and see whats in it?

Do vacuum cleaners work in space?

What is the best book on probability theory?

Are there any ways too increase my IQ, or am I forever destined for a path of mediocrity.

I like Christianity and science, but there's one thing that scares me in both disciplines: infinity Am I the only one?

Why is this board called Science & Math? Doesn't that imply Math isn't a science?

knowing the inherent inefficiency of solar, the lack of abundant sunshine in germany, and the internet's propensity to exaggerate, distort, and LIE (ahem- algore), I highly doubt the validity of this statement. Will /sci/ do me a solid and vette this? Thanks.

Why do people on here ridicule the reliability of an IQ test so much, when they are colloquially accepted as the best measure of intelligence?

so what does /sci/ think about Ray Kurzweil?

How can a photon have no mass. If mass is M=E/c^2, does this mean a photon has no Energy either? What am I missing?

Hello /sci/. I'm looking through an example on triple integrals as shown in my picture, the actual problem is above the line, below is how to solve it. In addition z is between 0 and 4. What I don't understand is, why does the r come in as a factor in the cylindrical coordinate function? By substituting the x with r*cos? and y with r*sin? i get z*e^(r^2), not z*(e^(r^2))*r. What am I doing wrong?

How do I get taller? 5'6'' here and 22 years old. I'm sick of feeling like a child in comparison to everyone else my age, especially around women.

> yfw were just energy gradients

Hey guys if there are + and - charged particles could there be × and ÷ charged ones? Perhaps these make up dark matter and we haven't found them because no one's looking for them?

are there real numbers that can't be written in terms of all mathematics constructions we know for representing numbers?
