Your post is difficult to read. Can you rewrite it using Latex?
The problem is t(x)=I(0)exp(-a(x)) which is also roughly equal to =I(0)[1-a(x)] but what if we have s(x)=t(xo-m*cos(wt))
find the fourier transform of s(x):
which is given by:
S(y)= int(s(x)*exp(-i*x*y))dx
= int(t(xo-m*cos(wt)*exp(-i*xo*y))dxo
and now is where i get lost the next line in the solution is:
= exp(-i*m*y*cos(wt))*int(t(xo)*exp(-i*xo*y))dxo
i dont understand how they took out the mcos(wt) from the integration, can someone help giving me direction to get to this line before continuing
we have we have
fourier transform
this is the line i am lost line ,i dont understand how they took out the mcos(wt) from the integration, can someone help giving me direction to get to this line before continuing
