Plotting phase and magnitude -

plotting phase and magnitude - urgent

hi,

Using the Fourier transform integrals i find the Fourier transform of a function to be

x(w) = j (5To/2) { sinc [5To/2 (W+Wo)] - sinc[5To/2 (W-Wo)] }

Can someone pls tell me how to find the phase and the magnitude from this equation and how to plot them both. I am stuck here and don't know how to proceed.

The other 2 functions for which I need to do th above are
x(w) = 4sin^2 ((pi/4)*W) / W
and

x(t) = A/pi + A/2 sin(Wot) - 2A/3pi Cos(2WoT) - 2A/15pi cos(4Wot)...

thanks a lot

For a mathematical definition of phase, see https://en.wikipedia.org/wiki/Phase_(waves)
The amplitude is the coefficient in front of the sine or cosine functions.
If you mean the period, then it is the value $p$ obtained by $\sin(t+p)=\sin(t)$ for all $t$.
