I am part of a CubeSat team at my school, and one job that I'm currently tasked with is figuring out how to build a transmitting/receiving system that will fit into our satellite. As a result, I am wondering if anyone knows if there are any good, affordable devices that will let me basically...

Hey... I was just thinking... Does anyone know how to extract the electron gun from an old CRT so that it is left intact? Basically, I want to remove it so that I can play with the electron beam/use it for other experiments/ etc. Please tell me.

Hm, Then in that case, yeah, your particular solution is right. Note, though, that when you add the particular and homogeneous solutions together, you do NOT get rid of either of the exponential forms. One is ex and the other is e2x, so in this case, your full solution should take the form...

Hey there, Let me see if I understand what you're saying. So you say that for the differential equation you gave: y" - 2y' = x + e2 You found your homogeneous solution: yh = C1 + C2e2x And your particular solution: yp = Ax + B + Cex I think you might have made a mistake in there...
