Linear Alg MAS3114 2481 Class-A Prof. JLF King 20Nov2006 For questions A1 and A2 please show no work; no partial credit. Write DNE , for “Does Not Exist”, if the indicated operation cannot be performed. Do not make approximations. Please be sure to write expressions unambiguously e.g, the expression “1 /a + b should be bracketed either [1 /a ]+ b or 1 / [ a + b ]. Be careful with negative signs! A1: Let A := ± 2 3 4 - 1 - 1 1 - 2 0 1 ² , B := h 2 0 2 0 - 1 5 i , and let u := h 1 2 0 i , w := h 1 2 - 1 i . a So AB = .............. . BA = .............. . b Circle those of the following vectors which are in Spn { u , w } . v 1 := ( 2 , 4 , 6 ) v 2 := ( 2 , 4 , - 6 ) v 3 := ( 0 , 0 , 0 ) . For the next two parts, let AT mean “Always True”, let AF mean “Always False”, let Nei mean “NEIther always true nor always false”. Please ± ² ³ ´ circle the correct response. Below, u , v , w represent non-zero vectors in R 4 . c
