Im looking for a website or book that I can look up any kind of equation in, does anyone know of a website or book like this?
Depends on how exactly you’re looking it up. By name, perhaps? One possibility is Mathworld. Does this do what you want?
CRC Press sells a lot of reference books. They might have a good one.
Any kind of equations are good. What Im mostly looking for is basic equations for science, math and finances or interesting equations like the one for time dilation that can tell you have slow you have aged at when traveling at a certain speed for a certain amount of time.
Mathworld seems to have a lot, Im still shifting through it, I can’t believe I didn’t come across this site before.
Yeah, the OP is like asking for a book where you could look up any kind of sentence. If you’re looking for just random equations (for an art project or something similar), then I’m sure you could get a lot out of Mathworld, and its sister sites: Eric Weisstein’s World of Physics, Chemistry, and Astronomy.
An entertaining and enlightening source for all things, including equations, geometric: The Geometry Junkyard
I get the impression you’re looking for window dressing more than edification, neh?
I have some equations on my site:
Quadratic Equation
Time Dilation
Circle Sphere & Cylinder
There are others but you’ll have to look for them. I’m not going to list all of them.
Good luck.
