Note: it’s not hard to check your answers withx < 0 problems.
, if these

y 2 ( x) = 3x
3 cos(x) ,x IR (a) Use the deﬁnition to show that y1 (x), y2 (x) are linearly dependent
on x 0.
(b) Use the deﬁnition show that y1 (x), y2 (x) are linearly dependent on
x < 0.
(c) Use the deﬁnition show that y1 (x), y2 (x) are linearly...
