The inverse of a 2x2 matrix:[a b][c d]is given by__1___[d -b]ad - bc [-c a]ad - bc is the determinant of the matrix; if this is 0 the matrix has no inverse.The inverse of a 2x2 matrix is also a 2x2 matrix.The browser used here is not really suitable to give details of the inverse of a general matrix.Non-singular square matrices have inverses and they can always be found. Singular, or non-square matrices do not have a proper inverses but canonical inverses for these do exist.
A c before a number refers to circa. This is often used in describing the year something took place, saying that it took place near or around the number given.
False. * * * * * No, it is true. It is false if the line is a vector but not otherwise.
Transpose means swap places. In maths, the term is usually used for matrices. It means truning the matrix around so that its rows become columns and columns become rows.
x - 2y = -4 2x - y = 1 To solve this system of equations, I used matrices, and got x = 2 and y = 3.
