Here is the question:
Given that:
L{Cos(9t)/sqrt(pi*t)} = e^(-9/s)/sqrt(s)
Find the laplace transformation of sqrt(t/pi)*Cos(9t)
L{sqrt(t/pi)*Cos(9t)} = ?
First I multiply the question by t/sqrt(t^2) which = 1
and question becomes
L(t * Cos(9t)/sqrt(pi*t))
so by the theorem of Differentiation of Transforms
my answer comes out to be
(-1)^1 F'(s)
= e^(-9/s)/(2e^(3/2)) - (9e^(-9/s)/s^(5/2))
But it's wrong... please tell me what I did wrong!!
Thank You!!
