hint a) let [y1 y2]' = A * [x 2x]'
the condition is y2/y1 = 2 for all x
hint b) A is non-singular means det(A)<>0
I need some help on this question and a couple explanations on some terms.
, where k is a constant.
A transformation is represented by the matrix A.
a) Find the value of k for which the line y=2x is mapped onto itself under T
b) show that A is non-singular for all values of k
i need help on both parts of the question, and waht is ment by non-singular?
