Unformatted text preview: x 3 , or . 7) Show that in order for the system below to be consistent, a , b , and c must satisfy c=a+b . The augmented matrix is which reduces to . In order for the system to be consistent the last row must be all 0’s, so a + b –c = 0 or c = a + b. 8) Let a and b be constants. Solve the following system. The augmented matrix is which reduces to . So . 9) Solve the following system of linear equations for the angles , and where , and . Let x 1 = sin( ), x 2 = cos( ) and x 3 = tan( ), then or which reduces to So sin( ) = 1, cos( ) = 1, tan( ) = 0 Or , and...
