Web1 Answer Sorted by: 1 The standard flow looks more or less like this: syms t s Y % Find Laplace transform of right-hand side. RHS = laplace (27*cos (2*t)+6*sin (t)); % Find transforms of first two derivatives using % initial conditions y (0) = -1 and y' (0) = -2. WebTo determine the default variable that MATLAB differentiates with respect to, use symvar: symvar (f,1) ans = t Calculate the second derivative of f with respect to t: diff (f,t,2) This command returns ans = -s^2*sin (s*t) Note that diff (f,2) returns the same answer because t is the default variable.
