Please answer part d and e

Title Subtitle 15 3. The following wavefunctions (N.B. selection is dependent on the parity of the quantum number) have been proposed as solutions for a particle in an infinitely deep symmetric well with zero potential energy at walls located at -L/2 and L/2: Todd (x) = COS L even (x) = sin nix where 'odd' and 'even' refer to the parity of n, i.e. if n = 1, 3, 5 ... then this is 'odd' etc. d) Determine an expression for the kinetic energy for the particle, given your assigned quantum number n, in Table 1. e) Showing working, predict the probability of the particle, with quantum number n, existing within the range a s x s b, where n,a and b are given in Table 1.
