    Undergrad Can Vector v Be Expressed as a Linear Combination of v1, v2, v3, and v4?

    Hi I apologize for posting a homework question here. Actually i was new to this site that's why i wasn't aware of such rules. But i'll keep that in mind in future

    Hey HALLSOFIVY Thanks a ton for help. The question which i got from my professor is exactly the same which I mentioned. I think there's some problem in question itself. i will ask about it from my professor and will post the reply soon here. Thanks :)

    Undergrad Can Vector v Be Expressed as a Linear Combination of v1, v2, v3, and v4?

    Hi Ya the question i mentioned is absolutely correct. The equation is: 7=c1+2c2+11c3+4c4 9=4c1+ 5c2+ 14c3+ 3c4 6=2c1+3c2+12c3+2c4 8=8c1+9c2+18c3+c4 This equation is showing no answer becuse the matrix formed by using coefficients of "c1,c2,c3,c4" is singular. So is there any way...

    Undergrad Can Vector v Be Expressed as a Linear Combination of v1, v2, v3, and v4?

    Hi HallsOfIvy Ya i did tried it by myself. Bu am not able to find values for "c1,c2,c3,c4". According to me it gives no solution. So how can I express "v" as linear combination of "v1,v2,v3,v4"?

    HI everyone, v1=[1 4 2 8]^t v2=[2 5 3 9]^t v3=[11 14 12 18]^t v4=[4 3 2 1]^t I have to express vector v=[7 9 6 8]^t in two ways as a linear combination v=c1v1+c2v2+c3v3+c4v4 of {v1,v2,v3,v4} Please reply as soon as possible. Thank You in advance.
