Let L be the smallest digit appearing in your UID and let R be the largest digit appearing in your UID. The function f(x) = (x-L)(R-x) opens down and crosses the x-axis at x = L and x = R. Use int to find the area below f(x) on the interval [L, R]. Assign the result to a5. Let K be your UID and let L be the number obtained by reversing the digits of your UID. Use solve to solve the system of equations xy = K and x + y = L. Assign the result to a6. Let p(x) be the degree 8 or lower polynomial constructed using coefficients from your UID in order. For example if your UID is 318554213 then the values 3, 1,8,... become the coefficients and we get p(x) = 3x + 1x + 8x6 + 5x + 5x + 4x + 2x + 1x +3. Use diff to calculate d p(x). Assign the result to the symbolic function f(x). dx Let A be the leftmost nonzero digit of your UID and let B be the second-leftmost nonzero digit in your UID. Use vpasolve to find the 2A+1 approximate single x-intercept for the function y = x oBx + e . Assign the result to a8.
