Spectacular explanation! Thank you! I'm pretty adept at creating spreadsheets so this will be a minor task.

Well, they do actually. It's a tablet called the smallvox. However, I still need this wonderful capability myself to keep things consistent in my story.

Summary:: Writing a YA Space Opera series, but I'm lost on trying to create a formula for calculating "Earthbirth Days" Short run down: Earth was no long hospitable to humans so we left to colonize a new planet, Nemesyne. People on Nemesyne still celebrate their "Earthbirth Days" and count...

Homework Statement I'm also having trouble with these: provide the names and sketch the following surfaces: x2+y2+z2=16 x2+y2=9 x2+2y2+4z2=16 z=-√(9-x2-y2) z=√x2+y2 z=x2+y2 Homework Equations The Attempt at a Solution So for the first one it's a sphere with radius of 4...

Homework Statement I'm having some trouble remembering how to do this in a refresher course... sketch the intersection of (x^2)+(y^2)+(z^2)=3 and z<0 sketch the intersection of z=2(x^2)+2(y^2) and z=4-(x^2)-(y^2) Homework Equations The Attempt at a Solution I think the...

OH! Haha, thank you!

Homework Statement If electrons can be ejected from a silver surface using light with wavelengths as large as 262 nm. What is the work function for silver? Homework Equations work function=hf c=f\lambda The Attempt at a Solution Given the wavelength, I solved for f =...

Really? It's what our book gives us :/ Mind telling me what I should be using?

Homework Statement Find the speed (as a decimal fraction of c) and momentum of a proton that has a kinetic energy of 1000MeV. The proton mass is 1.673x10-27kg, or 938 MeV/c2. Homework Equations KE= (1/2)mv2 KE= \gammamc2 p=mv \gamma=1/(sqrt(1-(v2/c2))) The Attempt at a Solution...

Is gryochronology a type of photometric measurement or no? I've got it listed as such under my class notes, but I don't see how it could be...

Ah! I missed (-1,1), thank you! And I got eigenvalues unnecessarily mixed up in all this (where the lamdas came from), thanks!

Homework Statement Find the critical points and use the second derivative test to decide if your critical points are local maxima, local minima, or saddle points. f(x,y)=x4+y4+4xy The Attempt at a Solution so I took the gradient to get: <4x3+4y, 4y3+4x> I know I need to set...

Nevermind! http://www.gamedev.net/community/forums/topic.asp?topic_id=586469 This explains it.

Ah, okay thank you. I'm so awful at comp science. After fixing that I got just one more error: LINK : fatal error LNK1561: entry point must be defined any ideas??

Homework Statement This program simulates the actions of two elevators in a building. The building has MAXFLOOR floors - make this a program constant and set it to 15. You need to write an Elevator class. This class will have only one member variable, which is the floor of the building on...
