 HW Helper P: 2,567 Note there's no qualititative difference between the x and y directions. You could write the wavefunction more symmetrically as: $$\psi_{nm} = C \sin \left( n \pi \frac{x-(-A)}{A-(-A)} \right) \sin \left( m\pi \frac{y-0}{B-0}\right)$$ They just used some trig identities to rewrite this.
