- Q1. Show that the first four Laguerre polynomials [named for the French mathematician Edmond Laguerre (1834–1886)] P1 = 1, P, = 1- x, P=2 – 4x + x², and P4 = 6 – 18x + 9x² – x3 %3! form a basis for P3.arrow_forwards = (6 4 1) (3 −5 1) (8 13 6) (0 6 9) explain why S is not a basis for R3arrow_forwardVerify that each of the sets in Examples 1– 4 satisfies the axioms fora vector space.
