Then the pair (( A < sub > i </ sub >)< sub > i ∈ I </ sub >, ( f < sub > ij </ sub >)< sub > i ≤ j ∈ I </ sub >) is called an inverse system of groups and morphisms over I, and the morphisms f < sub > ij </ sub > are called the transition morphisms of the system.

Then, hit the inverse tangent key ( or tan < sup >- 1 </ sup >) and the answer just calculated.

Then each double coset is of the form HxK, and G is partitioned into its ( H, K ) double cosets ; each of them is a union of ordinary right cosets Hy of H in G and left cosets zK of K in G. In another aspect, these are in fact orbits for the group action of H × K on G with H acting by left multiplication and K by inverse right multiplication.

Let f < sup >− 1 </ sup > denote the inverse function of f. Then, for all a ∈ and b ∈,

Then the matrices would progress through the machine, where a special keying system on one end of the matrix, unique for each character, would allow the matrix to drop only into the correct storage slot, ready for future use.

Then the terms of can be tabulated as elements of an matrix:

Let vectors and let denote the matrix with elements of a and b. Then the area of the parallelogram generated by a and b is equal to.

Then the area of the parallelogram with vertices at a, b and c is equivalent to the absolute value of the determinant of a matrix built using a, b and c as rows with the last column padded using ones as follows:

Then the existence of an eigenvalue is equivalent to the ideal generated by ( the relations satisfied by ) being non-empty, which exactly generalizes the usual proof of existence of an eigenvalue existing for a single matrix over an algebraically closed field by showing that the characteristic polynomial has a zero.

Then by Schur decomposition it is unitary similar to an upper-triangular matrix, say, B.

Then, we sort the list by coordinates, and update the matrix as we go.

Then M is called a symplectic matrix if it satisfies the condition

Then, the individual normal equation matrices were combined and the resultant matrix solved to obtain the positions and the parameters.

Then, as the matrix product is associative,

Then the Gaussian curvature of the surface at p is the determinant of the Hessian matrix of f ( being the product of the eigenvalues of the Hessian ).

Then the Jacobian matrix is

Then in 2 we show that any line involution with the properties that ( A ) It has no complex of invariant lines, and ( B ) Its singular lines form a complex consisting exclusively of the lines which meet a twisted curve, is necessarily of the type discussed in 1.

Then, too, the utmost clinical flexibility is necessary in judiciously combining carefully timed family-oriented home visits, single and group office interviews, and appropriate telephone follow-up calls, if the worker is to be genuinely accessible and if the predicted unhealthy outcome is to be actually averted in accordance with the principles of preventive intervention.
