Convert
y" – 3t y' +3 y= cos(5 t)
into a system of first-order equations.
a) O [x', =x,, x', = -3 x, + 3 t x, – 5 sin(5 t)]
b) O [r, =x, x', = - 3 t x, + 3 x, – cos(5 t)]
c) O [x, =x2, x'2 = -3 t x, – 3 x, – 5 sin(5 t)]
d) O [r =x x'2 = 3 x, + 3 t x, + cos(5 t)]
[* = *, x,= -3 x, +3 t x, + cos(5 t)]
f) O None of the above.
