Hello,
I don't know what is i in the answer of my script. Complex number? how can I simplify it? I need to get rid of i.
syms x(t) s
Dx = diff(x(t),t);
laplace(sin(t)*Dx,t,s)
ans =
- (s*laplace(x(t), t, s - 1i)*1i)/2 + (s*laplace(x(t), t, s + 1i)*1i)/2 - laplace(x(t), t, s - 1i)/2 - laplace(x(t), t, s + 1i)/2
Thank you for helping me

How could it possibly solve the final laplace? You are dealing with the unknown function x(t) !
