    Real and imaginary parts of wave function

    A very general question: What do the real and imaginary parts of a wave function correspond to physically? Cheers

    Mathematica Another Weird Mathematica Problem

    When you solve something and it gives answers like this: {σ -> 0.653831, μ -> 9.31514, γ -> 7.22386}, how do you get it to give {0.653831, 9.31514, 7.22386}, i.e a set without the symbols? Cheers,

    The behaviour of e^x near infinity and -infinity

    e^x goes to 1 as x goes to 0. e^x goes to 0 as x goes to negative infinity e^x goes to infinity as x goes to infinity (no limit) Is that what you're after?

    How do I find the derivative of one vector with respect to another?

    Thanks mate. I didn't expect such a long reply and one quite so theoretical. It'll take me a bit to mull over so cheers!

    How do I find the derivative of one vector with respect to another?

    What does it mean to operate with \frac{d}{\vec{v}} where v is a vector? Say you have another vector q, how do you do \frac{d\vec{v}} {d\vec{q}}[\itex]? What about [itex]\frac{d\vec{v}} {d\vec{v}}? (Can't remember how to do the proper font sorry)
