Eigenfunctions of second derivative operator

WebOperators An operator is a symbol which defines the mathematical operation to be cartried out on a function. Examples of operators: d/dx = first derivative with respect to x √ = take the square root of 3 = multiply by 3 Operations with operators: If A & B are operators & f is a function, then (A + B) f = Af + Bf A = d/dx, B = 3, f = f = x2 Web0 = (a1 − a2)∫ψ ∗ ψdτ. If a1 and a2 in Equation 4.5.10 are not equal, then the integral must be zero. This result proves that nondegenerate eigenfunctions of the same operator are orthogonal. . Two wavefunctions, ψ1(x) and ψ2(x), are said to be orthogonal if. ∫∞ − ∞ψ ∗ 1ψ2dx = 0. Consider two eigenstates of ˆA, ψa(x ...
