show that the Uncertainty Principle holds if the sigma's are reasonably defined widths

Initial Wavefunction. (a) Suppose M): m kxSskxskx+5 (28) 0 elsewhere for a free particle. Calculate and plot |'P(x, 0) I2 as a function of 5x, and Show that the Uncertainty Principle holds if the as are reasonably dened Widths. (Note that the usual standard deviation in this case cannot be calculated.)
