 Oct17 comment Need help with Determining a formula for a Resistance using a linear system for loop currents Okay, great. And the equations you found are considered a "linear system" for the loop currents? Oct17 comment Determinants of Variables I'm not sure about the rows in the middle. That's all that is given. Oct17 comment Determinants of Variables The size isn't given.

I think it can be any type of matrix. Oct3 comment Find a $4\times 4$ matrix $A$ where $A\neq I$ and $A^2 \neq I$, but $A^3 = I$. Fixed, accepted previous answers from those who have helped me. Oct3 accepted How do I determine linear independence when I don't know the values of the vectors? Oct3 accepted Show that the transformation T defined by $T(x_1, x_2)\; = \;…$ is NOT linear. Oct3 accepted A linear transformation $T$ is defined by $T(x_1, x_2)$ Find the image of the line that passes through the origin and point $(1,-1)$ Oct3 accepted How to solve / set up three equations three unknowns with a matrix?

Oct3 comment Find a $4\times 4$ matrix $A$ where $A\neq I$ and $A^2 \neq I$, but $A^3 = I$. Sure! Will certainly do.

Oct3 comment What do I do if I've been asked to find the preimage of a vector, but the inverse of the Transformation Matrix doesn't exist? Or would x1 and x2 alone be a preimage?
