you got x, y pairs from somewhere (maybe an experiment) and plug into program and pops up a simple equation that best models the pairs (e.g. y = e^x) and curve fitted as well.
The reason I'm asking is cause I made such a program, and want to know if such a thing is useful to others.
How? I've been looking but the only thing I get is the double slit experiment.
How do you build a device that shoots one electron at a time? I know how to build a device that shoots a whole stream of electrons. But 1 at a time! How is it possible to get to such high granularity?
There are these things where you can write on by putting pressure, and by lifting the paper it clears. I really want one to like write ideas & scratch work and stuff down and quickly erase it.
I used to have one a long time ago and looking for it again
given z = (0, 0, 0, 1), and v = (0, x, y, z),
and the following properties hold
v \times u = L
L \times v = u
u \times L = v
v, u, l, and z are unit quaternions
In other words; we define forward (v), up (u) and right(L), find a unit quaternion that when you apply...
Hi, I'm trying to solve the following equation
y'' + by' = a
But my answer doesn't make sense:
an object is flying through space, with velocity could be approximated as:
v_next = v_current + a*dt - damp*v*dt
dt - time increment taken repetitively
a - acceleration
damp - a...
Hello everyone :)
There is an alien that just came to earth and is having trouble recognizing peoples faces. We also have trouble recognizing his face; where his eye is on one hand and a mouth on the other. Luckily for us the alien understands our language and simple colours.
The task is...
Iam asked to tutor a student in highschool math (10) and was wondering where may I find a variety of questions. I thought about making questions up myself but it is more time consumeing than I initially have thought.
I don't know which forum to post this question? If another forum area is...
