Berechne die folgenden Vektoren:

´a = ((6,5,3,4), (1,8,2,2), (4,9,3,2), (4,9,7,1)) * ((4),(2),(3),(1))´

´b = ((2,0,0,0), (0,1,0,0), (0,0,3,0), (0,0,0,1)) * ((x),(y),(z),(1))´

´c = ((alpha,0,0,1), (0,0,beta,0), (gamma,0,1,delta), (0,zeta,0,eta)) * ((x),(y),(z),(1))´

Approach

´a = ((6,5,3,4),(1,8,2,2),(4,9,3,2),(4,9,7,1)) * ((4),(2),(3),(1)) = ((6 * 4+5*2+3*3+4*1),(1*4+8*2+2*3+2*1),(4*4+9*2+3*3+2*1),(4*4+9*2+7*3+1*1)) = ((47),(28),(45),(56))´

´b = ((2,0,0,0),(0,1,0,0),(0,0,3,0),(0,0,0,1)) * ((x),(y),(z),(1)) = ((2x),(y),(3z),(1))´

´c = ((alpha,0,0,1),(0,0,beta,0),(gamma,0,1,delta),(0,zeta,0,eta)) * ((x),(y),(z),(1)) = ((alpha *x + 1),(beta * z),(gamma * x + z + \delta ),(zeta * beta + eta))´


Solution

  • ´a = ((47),(28),(45),(56))´ ´b = ((2x),(y),(3z),(1))´ ´c = ((alpha *x + 1),(beta * z),(gamma * x + z + \delta ),(zeta * beta + eta))´
