Given a vector, t, of length n, write down the matlab expressions that will correctly compute the following. for this question you don't need to include the whole code, you only need to include a single matlab expression for each signal. a. in(2t2) b. e(1 cos(3t)) c. cos2(t) sin d. tan'(t) (this i e. cot(t) f. sec(t)+ cot(t) 1 t) the inverse tangent function)
