Yes, it is a talking book haha. (Don't know how to do that quote thing you did)
Correct me if I am wrong but because the current source is the load, I thought I just turn it into an open circuit then solve for resistance from there.
I could just be not understand the whole process...

Homework Statement
dy/dt=y((3t^2)-1), y(1)=-2
Homework Equations
Basic integrals
The Attempt at a Solution
integrate on both sides: dy/y=dt((3t^2)-1)
========>ln(y)=(t^3)-t+c
========>y=e^((t^3)-t+c)
========>y=e^((t^3)-t)e^(c)
I am not sure if its some e rule that I forgot...

I am making a coil gun for my physics project and I am wondering if it is better to use a thick wire or a thin wire for the coiling process. (both are magnetic wire)
Also, when I coil it, am I supposed to make only one layer of coil as opposed to several layers?
Thanks in advance.
Homework Statement
A 3x3 matrix with all 9 of the numbers being .3
Find all the eigenvalues.
Homework Equations
The Attempt at a Solution
I worked through it and I ended up with (l=lamda) l^3-.9l^2+.54l-.162=0
With my calculator I found one of the values, which means that there...
Can you explain to me how d=a, since a+d=0?
Also since I am actually having a hard time learning this on my own, can you tell me what you mean by "elements" and "linear sum"?
Homework Statement
Find a basis for each of the spaces and determine its dimension:
The space of all matrices A=[a b, c d] (2x2 matrix) in R^(2x2) such that a+d=0

So I jumped at this question without knowing too much about spaces and...
Homework Statement
There are two questions in my problem set that are giving me a hard time:
1. The cross product of two vectors in R^3 is defined by [a1, a2, a3]X[b1, b2, b3]=[a2b3-a3b2, a3b1-a1b3, a1b2-a2b1] (they are all one column) Consider an arbitrary vector v in R^3. Is the...
Homework Statement
Consider a linear system of four equations with three unknowns. We are told that the system has a unique solution. What does the rref of the co efficient matrix look like?
Homework Equations
The Attempt at a Solution
When it says "unique solution" I'm going to...
Every leading coefficient is 1 and is the only nonzero entry in its column.
From the looks of it, it looks like it follows those properties, but I'm just confused if it is still rref if everything is 0, since it doesn't have a leading 1.
According to wikipedia, it is:
In linear algebra a matrix is in row echelon form if
* All nonzero rows (rows with at least one nonzero element) are above any rows of all zeroes, and
* The leading coefficient (the first nonzero number from the left, also called the pivot) of a...
