Question:

(a) By drawing rough graphs, satisfy yourself that ψ₁ is even about the center of the box. That is, ψ₁(x) = ψ₁(a − x). Satisfy yourself that ψ₂ is odd about the center of box.
(b) Draw a rough graph of the product ψ₁ψ₂ and satisfy yourself that the integral of this product from x = 0 to x = a vanishes.
