Question

how do i take the Laplace transform of a periodic function how do i take the Laplace transform of a periodic function @Mathematics

Answer 1

Do you have a table of transformations?

If u dont have one u may calculate using the definition...
we know from Euler's Formula that sin x = (exp(-jx)-exp(jx))/2j and cos x s = (exp(-jx)+exp(jx))/2 and then integrate it!

Answer 2

well my function looks like this

so it has a period of 2 and
f(t) = -t ; -1 ≤ t ≤ 0
= t ; 0 ≤ t ≤ 1
