Here is the question. a hollow, thin walled insulating cylinder of radius b and height h has charge Q uniformly distributed over its surface. Calculate the electric potential and field at all points along the z axis of the tube.
Outside the tube
Inside the tube.

I need to derive the expression for the gradient operator in spherical coordinates.
I know the following
R =sqrt(x^2+y^2+z^2)
theta, call it %, = arctan sqrt(x^2+y^2)/z
phi, arctan (y/x)
Using dT/dx= dT/dR*dr/dx+dT/d%*d%/dx+dT/dphi*dphi/dx, do partial derivates...
dR/dx =...
I need help. For this problem, you have to use the Gram-Schmidt process to make it orthogonal.
My trouble is finding the bais for the kernel of the linear map
L: R4 -> R1 defined by L([a,b,c,d)]=a-b-2c+d
I know the dimension of the kernel is 3, but how?
I have tried setting it...

Let T ={ [1, 0], [1, 1] }be a basis for R2 .
Given that Transition matrix P s←t
[ 2, 3 ; -1, 2],
find the basis S for R2.
Here is what I think...I started by letting v being any vector...
[1,0] and [0,1] and applied them to the transition...
I need some help to understand the concepts of span, basis, and dimension.
1-How do you determine if a set of vectors [in matrix form] span a region?
-Do you set the given matrix set to arbitary numbers and see if
there is a unique, infinite, or no solution?
ie, set a 4X4...
