Thanks y'all! I'll be trying a little later this afternoon.

Homework Statement I've been having problems with a number of these things, here's the first one: y'' -2y' -3y = -3te-t Homework Equations I know that the general solution will be y = yh + yp where yh is the general solution to the homogeneous equation, and yp is the particular...

The exact wording of the problems is what I wrote. For Q1, just imagine a coeffecient matrix, now imagine them listed as column vectors V1-V3 instead.

Homework Statement Q1: Find the value(s) of h for which the vectors are linearly dependent. Justify your answer. Q2: The linear transformation T is defined by T(x)=Ax. Find a vector x whose image under T is b and determine whether x is unique.Homework Equations Q1: I'm going to write the...

I should have said that I didn't solve it COMPLETELY. I took it to reduced echelon form and confirmed that there was no row with a pivot in the augmented column, or in other words, of the form [0 0 0 b] where b is nonzero. Thanks for the tip about what seems like some sort of column...

Jon, I haven't learned how to perform an operation like that yet. I obviously notice that x2 = -x3, but don't know what that means yet. I reworked the problem and very quickly found where I made a careless mistake, and amend my answer to "The system is consistent." Mark, you said you took it...

Thanks for the quick response, Mark. I'm going to rework it. Am I wrong to think that if a row (x1 - x4 in this case) is all 0's, and the other side (the constant - I guess) is non-zero, that the system is inconsistent? In other words, I thought that by rule 0(x1) + 0(x2) + 0(x3) + 0(x4) = C...

Apparently the board reduces more than 1 space to 1 space. Maybe I'll go back and put in slashes.

Homework Statement Determine if the system is consistent. Do not completely solve the system. I don't know if there's an easy way to input a matrix. These are the numbers from an augmented matrix: 2 / 0 / 0 / -4 / -10 0 / 3 / 3 / 0 / 0 0 / 0 / 1 / 4 / -1 -3 / 2 / 3 / 1 / 5Homework Equations...

I don't remember much about that 1211 class. What I'm probably going to do is buy the book that the school I'm going to take 1212 with uses, because I believe it's one book for both semesters. Thanks for the advice!

Oh, no trouble at all! I'm definitely going to shoot for GT, but otherwise I might just have to hope for the best with SPSU. This is encouraging, at the very least. Would ABET accreditation affect my school prospects and job prospects, or just job prospects? In other words, if I could...

I took the first part of the college-level introductory chemistry classes (it's CHEM 1211 here). I took it a long time ago - 2002. When I took it, I didn't pay attention, it's a miracle I passed the class at all. And now I need the second part of the class. I'm worried that I'll be missing...

Thanks for the replies everyone. Yes, Farmergregor, I am unfortunately ineligible for HOPE. I graduated from H.S. in 2001 and really tanked my GPA for 2 years. I started taking classes again in January 2010, and am climbing out of the hole that I've dug for myself. While going to GT and...

That really depends on what you want to do with yourself after you finish school. Is your interest in physics a pure interest in the science itself, or in its application? If the answer is the former, then get a degree in physics. If it's the latter, get an engineering degree and back that up...

I've got one more semester left finishing up the periphery work before I transfer to a school with an EE degree to begin the core work of a program. I'm right at Georgia Tech's doorstep (although I wouldn't be able to live at home with the parents), but I don't know if paying for GT is a...
