(a) Using a trig identity, write x(t) = cos(5t) — sin(5t) using only one cosine function. - x(t) = help (formulas) = - - cos(5t) sin(5t) using only one cosine function. (b) Using a trig identity, write (t) x(t) = help (formulas) (c) Using a trig identity, write (t) = e - - -5t(cos(5t) — sin(5t)) using only one cosine function in your answer.
