The functions ¢1(x) and ø2(x) are normalized: d φ( (α) φι(α) dx 0(x) 62(x) = 1 = 1 -00 -00 and are mutually orthogonal dx oi(x) $2(x) dx 4i(x) $1(x) = 0 . Is the function b_(x) = ¢1(x) – $2(x) normalized? If not, determine its normalization constant and write the formula for the normalized y_ (x). Is the function +(x) = ¢1(x) + ¢2(x) %3D orthogonal to _(x)?

The first screenshot displays the question, and the second screenshot displays the section of the book that's relevant to the problem. So far, there have been two incorrect answers given: a.) 2.82 x e^-(1.51 x 10^12), and b.) (1.60*10^-19)^-(2.04*10^11) If someone can solve this problem, it would be deeply appreciated!
