Because that is a sinusoidal function. What is there to analyze?I couldn't understand that why the fourier integral is meaningless for f(x)=A*cos(ax) ?
Any comments will be appreciated.
The Fourier integral gives two delta functions. That is good enough for physicists.I couldn't understand that why the fourier integral is meaningless for f(x)=A*cos(ax) ?
Any comments will be appreciated.
