Tell me which one is true and Which one is false ?

IIOT or O F : The Wronskian of a fundamental set of solutions to the
differential equation y"(x) + y'(x) – 12y(x) = 0 is W(y1, y2)(x) = e-.
а.
b. OT or OF : The problem r"(t) + 2ca' (t) + wix(t) = 0 has no damping if
c = 0.
c. OT or OF : A certain differential equation has the solution
y(t) = e-/2[cos(5t) + sin(5t)] This solution can also be written in the form
y(t) = e-/2 cos(5t – 7/4).
