I attend UC Davis and have a total GPA of about 3.3. I recently took the general GRE and earned a 158 quantitative and a 154 verbal. I am taking the physics GRE this coming saturday, which I anticipate getting a mediocre score. I am currently looking at applying to a few universities: Carnige...

Awesome thanks.

I have a homework problem which asks me to compute the second and third excited states of the harmonic oscillator. The function we must compute involves taking the ladder operator to the n-power. My question is this: because the ladder operator appears as so, -ip + mwx, and because I am using it...

Well I guess it actually does print the value. I am finding that when I get to higher order, the array should read: -2 0 4 2 but it actually reads 0 -2 2 4 I have a feeling it just requires a switch of variables, but I am a little unsure... edit: I realized the variables I had in the output...

Alright so I think I am getting closer. I figured that the k_order is the amount of times the recursion must be done. So if I want order 3, I have to do the recursion for order one, than order 2, than order 3, and output the array after doing order 3. So far, my code has been altered to this...

Alright thanks for the heads up. In the box in our text, it claims we should use arguments K_Order - order of the hermite polynomial, and NDMN - dimension of the array NARY. I was wondering if anyone knew what the difference in this number would be. NDMN should either be the size of the order...

Homework Statement I need to generate coefficients of hermite polynomials up to order k. Recursion will be used. Homework Equations a[n+1][k] = 2a[n][k-1] - 2na[n-1][k] The Attempt at a Solution Its not pretty, but here is my code. #include <iostream> #include <iomanip>...

If you look like a tourist, you are treated as such. Dont wear your money pouch like a fanny pack. When I was there people were very friendly even though we didnt speak any italian. The vatican is a must see. Go in the afternoon, the lines will be shorter and the tour will probably be more...

That equation tells you that if the car is moving at a constant velocity then the sum of the forces acting on it are all canceling. It does have momentum, which is what will be transferred in a collision (Along with kinetic energy). Momentum is mv and kinetic energy is 1/2mv^2

Why oh why didnt I take the BLUE pill?

For smoke I would recommend using high powered flashes. You shouldn't really have to be going all the way up to 1/1250 to get a sharp image of smoke. I would think even 1/320 would be sufficient, in which case you could lower your ISO to say 400 and increase that f stop to f8.

Did you just call baseball a hard hitting and rough tough game? :rolleyes: Soccer is a great game. People in America generally don't like it because they do not understand it. If you think soccer has no contact you are crazy... Watch any high level game and pay attention to the shirt grabbing...

If I am not mistaking I think you can just orient the coordinate system so the force is along one axis. I don't know any CS though.
