Why does the Laplace Transform not solve this

59 Views Asked by At

Suppose I have an equation like:

$\sin t=t\cos t$

If I take the Laplace transform of both sides I obtain:

$\frac{1}{s^2+1}=\frac{s^2-1}{(s^2+1)^2}$

Simplifying I obtain:

$\frac{s^2-1}{s^2+1}=1$

Taking the inverse laplace transform:

$ \delta(t)-2 \sin t = \delta(t) $

$ \sin t = 0 $

Apart from the solution $t=0$, this method does not yield the correct solution.

So my question is this:

Is this method a valid way to approach the problem, or is there a fundamental flaw with this approach?
