Question

Laplace transform:
L{e^(2t) * sin(10t)}?

Answer 1

i would help you if i knew how to. :l sorry!

Answer 2

use the definition

Answer 3

\[\int e^{-st}e^{2t}sin(10t)dt\to\ \int e^{-(s-2)t}sin(10t)dt\]

Answer 4

u = s-2

\[\int e^{-ut}sin(10)dt=\frac{10}{u^2+10^2}\to\ \frac{10}{(s-2)^2+10^2}\]

Answer 5

Thank you!

Answer 6

yw

Answer 7

with any luck i remembered the tabling for the sin correctly :)

Answer 8

I didn't remember it was one of the basic transforms :P
