A simple mathematic questions

[IC16]

Hi,

Would you please resolve the question,I will appreciate you.Thank you

F(w)=-2j∫1/t sinwtdt=? ( 0<t<∞)

I suggest you may use numerical integration rather than for close form of solution. The other approach would be to expand sinwt in series and integrate.

Here is the solution.

 

[eng_Semi]

I think that it may be solved by integration by parts

hi
F(w)=-2j∫1/t sinwtdt
if (<0t<∞) undefined

but

int((1/t)*sin(w*t))

ans =

-1/t^2*cos(w*t)

bye
