Ux + 5Uy = 1 + 4x^2

Find a particular solution U(x,y). I'm entirely clueless on solving PDE's, so a walkthrough and explanation would be greatly appreciated. Thanks!

I am planning to major in Physics in the upcoming year. I also would like to pursue a foreign language major and minor. Is there a language that is particularly helpful or useful to learn for physics majors interested in higher level study (post-grad as well)? I would like to go into research in physics in the long run.

Any help or suggestions are highly appreciated!

I recently purchased a 4gb geek squad flash drive. i tried to use it on my lenovo netbook running xp pro. the flash drive is detected as removable disk (E:), but when i go to My Computer and click on E:, i am prompted to insert a disk into drive E:. i tried this same geek squad flash drive on my gateway desktop running vista, and it worked perfectly. i went on the geek squad website looking for xp drivers, but i had no luck. does anyone have a solution? thanks.

I already had XP installed on my netbook, but I decided to install Fedora 13 also to dual os. When I installed Fedora, I partitioned my 160 gb hard drive into a 130 gb part for XP and a 30 gb part for Fedora. I am running low on my partition for XP (which I use primarily), and I want to remove the Fedora partition to clear up space. How do I delete the Fedora partition and combine the resulting unpartitioned space with the XP partition?

Thanks.

U0 = 2, U1 = 1, Un+1 = Un + Un-1 for n ≥ 1

Prove that

∞

∑ Un/10^(n+1) = 19/89

n=0

I can do this proof if I know how to change the recursive series Un (a general fibonacci series) to a geometric series.

I was told that A*p^n + B*q^n, where p = (1+sqrt(5))/2 and q is its conjugate, is equivalent to Un. I evaluated the series and it works.

Where did this fibonacci to geometric conversion come from? is there a proof for it? I don't understand it at all. Can anyone explain?

Thanks.

Let Un be the sequence of integers defined by the following recursion formula.

U0 = 2, U1 = 1, Un+1 = Un + Un-1 for n ≥ 1

Prove that

∞

∑ Un/10n+1 = 19/89

n=0

I've been spending hours on this problem. Can anyone help?

Did the advancements that occurred during this time period help or hurt the American agricultural community?

I am currently a junior in high school. I have taken the PSAT, SAT, and a couple AP tests. I spent a lot of time preparing for these tests, but I can never seem to get the result I want. My PSAT and SAT scores were below 1600, which is just unacceptable for me. I studied extremely hard for the statistics AP test, but I still didn't get a 5, while some of my friends who didn't study got a 5.

I know I am a pretty smart guy. In school I perform very well. I am 3rd of 529 in my class. I can never seem to do well on these tests, but I try harder than anyone. Do you know any tips to help me out with this problem? These tests are very important for college admission, and I'm trying to get into a prestigious, top school. Having low test grades won't help me out with that.

Thanks for any help.

I am trying to start an Improv Club at my high school. I'm a very big fan of the art of improvisational comedy and I'm sure many others share this appreciation.

My school requires all of its extracurricular clubs to incorporate some form of education, learning, and enrichment within the activities we do. What are some activities my improv club can do in order to meet this requirement? I believe that improv overall is enriching. It enables students to gain confidence while performing and it exercises our skills of thinking on our feet. What are some games/activites we can do as a group? Thanks!

I am considering to jailbreak my 2nd gen ipod touch. Is their a way i could create a restore point for my ipod so i can restore to its current state? i currently have many apps and personal preferences on it. If i don't like the jailbreak, i would like to be able to restore my ipod to its current state with all of my apps, music, videos, and preferences already on it. Is there a way to do this?

I currently have Windows Vista and nvidia graphics on my HP Pavilion dv2000. Im interested in trying Fedora 10, so i download the live iso for the 64 bit version so no permanent changes are made. When i boot the cd, Fedora goes through the loading process in its text mode. I am prompted to enter a localhost name and password. i entered "root", then "startx" in the text mode, and soon a message that says "fatal server error: no screens found". Then i cannot do anything else. I never see a GUI desktop. does anyone know a solution to this?

I want to try Fedora 9 on a live disk on my HP Pavilion dv2000 laptop. After burning the iso file onto a cd, I booted from the disk and Fedora started its process. After a while, it tells me to enter a localhost name and password, but i never set a login or password. I tried to enter random thing. I entered something for the localhost name, then tried to enter a password, but nothing shows up in the password form. Does anyone know a solution to this?

I live in Indiana, and I have a learner's permit. Do I need to be insured to the car I am driving in order to drive it? Hypothetically, If I get into a car accident while driving with a parent, will insurance take care of the cost of the damages even if I myself are not insured to the car, or will my parent have to pay for it straight up?

Answer: Because I'm big and easy.

Although it has a bit of a dirty meaning, overall i thought that the joke was clever and humerous, by my friends thought the opposite. they thought it was horrible. Your thoughts?

Let A, B, C, and D be points of a plane. Let P be the disk for which AB is a diameter, and Q the disk for which CD is a diameter. Assume that A,B do not belong to Q and C,D do not belong to P. Prove that segments AB and CD are disjoint.

I believe the term Disjoint refers to two sets that have no element in common. How exactly can you prove this is true?

Usually, my computer makes at least one daily system restore point, but for the past week, I realized it has not. I do need to use system restore because the machine has been running very slow. I couldn't find any restoration points because the machine hasn't been making any. I pressed the button to view restoration points from last month, but it won't let me view them. Anyone knows why this is happening and how i can fix it?
