... by reinforcing the alloy with carbon or boron fibres (man-made composites). The sails, formerly of the natural material cotton, are now made from the polymers nylon, Terylene or Kevlar, and, ... the economic constraint on the choice of materials is less severe - a far greater proportion of the cost of the structure is that associated with labour or with production and fabrication. .....

... expanding a subdeterminant of order (n − r) by elements from one row and their cofactors. If one of the column parameters of an rth cofactor of A n+1 is (n + 1), the cofactor does not contain the element ... a n+1,n+1 . If none of the row parameters is (n + 1), then the rth cofactor can be expanded by elements from its last row and their first cofactors. But first cofactors of an rth cofactor...
