loads(homes, businesses, ...) etc. Computers at the power station need to solve huge systems of non linear equations several times per minute, and as it turns out the best way to do it is a guess and check method based on newton's method. Newton's method requires a derivitave. When solving the system of equations for a multivariate context in newtons method, you use the jacobian matrix. If I had known that this was used for a problem like this in
Calculus III, I would have paid more attention to the meaning and conceptual properties of the jacobian matrix.

designed to define the jacobian matrix, and i see that that definition is a stub. I have a copy of the page before it was fixed. i'm posting it in the stub for jacobian matrix. I think, then, it would be a good idea to discuss whether we might want to combine the two into one page? I'm for this. I think the ideas neeed to be presented closely together in order for fluent comprehension, and a brief and clear page describing first the jacobian matrix, and then the jacobian, would be simple to construct as well as being a better way to present the topic.

Partial (and not Total) Derivatives are sufficient for it's existence. I thought that for a function to be differentiable then it also had to be continuous at the point in question; i.e. that all derivatives (Partial and Total) would exist. I suppose, for example, that if Z = f(X,Y) and if Y is constant then there would only be dZ/dX and that dZ/dY would be zero and therefore that the total derivative would not exist at the point. Could someone please clarify this for me. Thanks.
4999:. The two vectors define a square (the red part on the left), which get mapped to a distorted rectangle (the red part on the right). The jacobian defines a linear transformation at each point, shown here is its action on two basis vectors. The resulting vectors define a parallelepiped whose area is an approximation for the area of the distorted rectangle. The area of parallelepiped is equal to the jacobian determinant, and as the rectangle gets smaller the error goes to zero.

3130:=0; if you take spherical and set the polar (zenith) angle to pi/2 you will get an extra term in the radial derivative that is not supposed to be there in 2D. This is part of the reason why we use θ to mean azimuthal angle in 2D Polar but then change θ to the Zenith angle in spherical and let φ be the azimuthal angle. It is fundamentally wrong to think that spherical and polar coordinates are this simply related.)

Yes, and it's worse than that: phi is supposed to represent the azimuthal angle ( from z axis) while theta should stay in the x-y plane as it does in polar form. Will someone who's savvy with the formula code please correct the notation, both in the parameterization and in the Jacobian?

Went ahead and changed this to standard physics notation. Here we use θ as the polar (zenith) angle and φ as the azimuthal angle (x-y plane, angle from x-axis). It is OK to use θ as the azimuthal, but then the notation should be (r,φ,θ) or the map should be changed to

It would be nice to have a section on generalizations. Given a map f between two Riemannian manifolds (M, g_M) and (N, g_N) a generalization of the determinant of the Jacobian is given (if I'm not mistaken) by the ratio of the determinants of f^*(g_N) and g_M. --gm

That is, if i change the order of the functions, the determinant changes its signal. This is consistent with determinant properties, I know, but my point is: which is the "right" order of the equations? Apparently the functions are NOT ordered.

In (x,y) space, the function is defined as xy/sqrt(x^2+y^2), and so neither it nor its jacobian are defined at (x,y)=(0,0). The function is defined at (r,theta)=(0,0), and so is it's jacobian = (0,0). A taylor series will show this very easily.
