Vector equation

Let’s v = (1, 2, 1), u = (0, -1, 3) and w = (1, 0, 7) . Solve the vector equation c1 v + c2 u + c3 w = 0 for variables c1 c2, c3 and decide weather v, u and w are linear dependent or independent

Result

c1 = (Correct answer is: ) OK
c2 = (Correct answer is: 2 c1) Wrong answer
c3 = (Correct answer is: -c1) Wrong answer

Step-by-step explanation:

c1 1+c2 0+c3 1=0 c1 2+c2 (1)+c3 0=0 c1 1+c2 3+c3 7=0  c1+c3=0 2 c1c2=0 c1+3 c2+7 c3=0  c1=any c2=2 c1 c1=c3=c1
c2=2 c1
c3=c1



We will be pleased if You send us any improvements to this math problem. Thank you!
