Question

How do you find linear dependency/ind. for a 2x3 matrix, where all of the entries are either sin(t) or cos(t)?

Answer 1

factor this expression. check by multiplying factors. x^2y-xyb-abx+ab^2

Answer 2

Hm I do not follow that. The problems in the set so far just involve doing Wronskian, but since it's a 2x3 matrix, cannot do Wronskian.

Answer 3

can one column be written in terms of the other two
