Hey! Could anyone give me a pointer to what I'm doing wrong here? I would appreciate it(adsbygoogle = window.adsbygoogle || []).push({}); alot.

Use Laplace transform to determine a distribution f, which satisfies the equation

[H(t)t cos t] x f(t) = delta(t)

where x is convolution and delta the dirac function.

_______________________________

If I let H(t)t cos t = g(t) I could simplify the equation to

g(t) x f(t) = delta(t)

Simplified again to

G(t) F(t) = 1

F(t) = 1 / G(t)

To solve for G(t),

G(t) = -d/ds (cos t) = sin t - t cos t

Which gives

f(t) = 1 / (sin t - t cos t)

I belive I'm totally mistaken. :-)

Thanks for any help,
