Use the following equations: Dal P₁" (x) = (1-1²) 11/12 (1) P/(x). P/(x) = 27 (1) (x² - 1). (21+1) (1-\m) p (cos 8). Y" (0.4) = √ 4 (1+1)! To build Y and Y, and that they are normalized and orthogonal?

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!

Using your values for 7, calculate the average period Ibar (I) and its standard error. How does the error on the average period /bar (T) compares to the errors on the periods, I? What can you do to reduce the uncertainty on /bar (T)? What can you do to reduce the uncertainty on 7 ?

A high tech company uses a satellite to measure the size of features on the surface of the earth. They use this technology to measure a particular rectangular field and find it's length to be 444 ± 1.8 in meters and it's width to be 198 ± 1.63 in meters. They plan to report the perimeter (sum of two lengths and two widths) of the field as P± SP in units of yards. (1 meter = 1.094 yards) What is SP?
