A particle in an infinite one-dimensional square well with walls located at x = 0 and at x = a has a wave function given by the normalized wave function phi (x) = (2/sqrt(a)) [sin ((pi*x)/a)*cos((3*pi*x)/a)]
1. Discover the uncertainty in the position.
2. Discover the expectation value of the energy
3. Decide the expectation value of the position.
4. What energies would be found upon a measurement of energy?
