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 meHello,
