What is a determinant in math? What is the determinant of a matrix with a single entry of 2? If A is a 9 x 9 matrix with 7 pivots, what is the determinant of A? What is the determinant of a matrix with size 8x7? What does it mean when the determinant of a matrix is 0? Wha...
Coevolution does mean that any task you can do in one language should be as simple in the other. In the .NET Framework 4, both Visual Basic and C# have taken giant strides toward this goal, each adding a number of capabilities the other already had. Coevolution isn’t just about the ...
A matrix is a square or rectangular grid of values, surrounded by square brackets. The lines of numbers going from left to right are the matrix's rows; the lines of numbers going from top to bottom are the matrix's columns. MathHelp.com ...

One can consider the inverse problem: given the inverse of , does one have a nice formula for the inverse of the minor ? Trying to recover this directly from (2) looks somewhat messy. However, one can proceed as follows. Let denote the matrix (with the identity matrix), and let be ...
All the entries of the product matrix are found in this way. For instance, the sum of the products from row 2 of A and column 1 of B is the 2,1-entry of AB. Which is all well and good, but what does this look like in practice? What does matrix multiplication look like? When ...
