f(t)=3sin(t)+5cos(3t)
i am not familiar with laplace of sin and cos functions
anyone help?
Table of Laplace Transforms
Particularly,
Ive just tried to answer the question ...I would like to know if the answer i found is right..
Qn: laplace of (f(t)=3sin(t)+5cos(3t))
L{f(t)}=3L{sin(t)}+5L{cos(3t)}
=3(1/(s^2+1))+5(s/(s^2+9))
On further simplification
=5s^3+3s^2+5s+27/(s^2+1)(s^2+9)
