Yes. That's what I mean. Thanks for your reply. i thought I got it wrong. :)

Is there a way to know the points if I only have the vector coordinates and I can't use the origin as one of the points? For example, if I have vec(PQ) <-1,4,-5> . Is there a way to know the points of this vector?

Yes! I took all those courses. Right now I'm doing my thesis. After this I want to study in US.

I'm from the Philippines. Right now I'm taking up Master of Science in Physics . I'm currently doing my Thesis, my current GWA is 3.2. (1.0-4.0 scale) My undergrad degree is Bachelor of Secondary Education major in Physics. My GWA back then is 89. (We don't use 1.0-4.0 scale) Do you thing I...

The following are Maxwell's Relations right? \left(\frac{\partial s}{\partial v}\right)_{T} = \left(\frac{\partial p}{\partial T}\right)_{v} \left(\frac{\partial s}{\partial p}\right)_{T} = - \left(\frac{\partial v}{\partial T}\right)_{p} Are these all? And BTW, these are derived from the...

I've been reviewing for quite some time now. Don't get me wrong. Well, what I want now is to focus on some topics which most probably would be given in the exam. Thanks

Well, our test is this coming saturday. What do you think should I study for Matrix Mechanics?

So, for our comprehensive exam (MS Physics) we need to answer 4 out of 7 problems. Here are the topics. 1. Fundamental Postulates of Quantum Mechanics 2. Wave Mechanics 3. Angular Momenta 4. Matrix Mechanics 5. Harmonic Oscillator 6. Atoms 7. Approximation Methods So, where do you...

YES! Certainly! Thanks!

Thanks for the responses guys. I'm learning. But, let me show you the example I'm having difficulty understanding. So, in normalization. \int_{-∞}^{∞} |ψ(x)|^{2} \mathrm{d}x = 1 (I get this) Say our ψ(x) = A e^{-amx^2 / \hbar} So we have \int_{-∞}^{∞} |A e^{-amx^2 /...

How would you take the derivative of this? \int^{∞}_{0} e ^{\frac{-2amx^2}{\hbar}} What's the trick in doing integrals having infinity as one of its limit? Or what if the limit is from ∞ to -∞?

Why is the integral of an odd function ZERO?

So, I'm studying normalization (Quantum Mechanics). I came across examples of integrands which they say are odd. So, they say the integral of an odd function is zero. How would I know my integrand is odd? Thanks :)

All you need to do now is simplify :)) \frac{5}{3}x ^{3} + \frac{2}{3} x^{\frac{3}{2}} + \frac{4}{x}

\int \sqrt{x} dx = \int \ {x^{\frac{1}{2}}} dx = \frac{2}{3} x^{\frac{3}{2}}
