Q3) a Find laplace transform of X (t)= et sin 2t for t ≤ 0 also indicate R.O.C please solve step by step subject signal and systems

E) F) The convolution of x(t) with y(t) is commutative results in a function that does not have a Laplace Transform is p0a nonlinear operation involves a change from the time domain to the frequency domain. Which of the following can be used t-o replace sin(x) for small values of x? OC 1 1-x 1+x O x-2

2.2 Find the Laplace transform of the function cos2(t) using MATLAB  Attach matlab code and output screenshot.
