At At Determine e by first finding a fundamental matrix X(t) for x' = Ax and then using the formula e A = 21 92 First, find X(t). Choose the correct answer below. O A. X(t) = O B. X(t)= O C. X(t) = O D. X(t)= Next, find e e At = - e At (1-1) e-t e 2017-12-07] (3+1) et 3e5t 3e-t -t - e e -t e St -t 3e St 3e-t cos 5t -t 5t 3 e cos 5t 3 e sin 5t - e 5t 5t 3e St e 5t sin 5t = = X(t)X(0)-¹.
