A particle is confined in a one-dimensional potential that is proportional

to the absolute value of ?, where ?(?) = ? |?|, and ? is a real, positive constant. Use the

variational method with the trial wave function ?(?) = ? ?−??2, where ? is a normalization

constant and ? is a real, positive parameter to estimate the ground-state energy of this system. Note that this potential is an even function.
