Hi everybody I think that each mathematical concept is born due to a need in physical applications. In dynamics,the concepts of eigen vector and eigen value return to rotation a rigid body.in this way, a 3*3 matrix has 3 eigenvector,so there are 3 vectors in reality and for each eigen vector...

Hi Emily_A As "I like Serena" has written,you have two vectors,x and b. and you have a vector with 2 elements. Due to dimension given for A,I think this given vector would be x. so you must only multiply A by x and calculate b. In another idea, this vector can be b. So in the equation you must...

Hi Emily_A what does it mean "2 -4" in the second line in your problem?Please identify your problem.It must not be so complicated :)
