I'm pretty sure I got the right system reaction. My problem is whether I got the right system output. Did I?

Hey Fp!

When you multiplied X(s) with G(s), you appear to have multiplied x(t) instead with G(s).
Do you know how to find X(s) from x(t)?

HEy ILS :)

Hmm, I did not realize there is a X(s). What exactly is it in words?

X(s) is the so called Laplace Transform of x(t).
Typically you use a table with Laplace transforms and look it up.

For instance, the Laplace transform of x(t)=2 is X(s)=2/s.

Oh my, I wondered if I stepped out of the bounderies of my class material. I'll go ask my classmate and check, because I don't remember having learned about it.

Turns out it is indeed beyond the scope of our material. I went ahead of myself! Thanks anyway :)

Okay ;)
