Scan/photograph clearly.
If we can't read it, we will grade it as incorrect.
After you finish your answers, scan or carefully photograph your answer sheets
and create a single PDF with those images to upload
to the ELMS entry.
If your Windows machine doesn't have a "Print to PDF" option,
you might find the free

You cannot e-mail them to me.
Even though you are uploading to
the entry on ELMS,
be sure to write your name and section clearly on the top of the first page.
We might not grade all questions.
(1) Use constructive induction to derive a formula for: n Σ i3 i=1 Show all of your steps and work. Note that any time we have a summation of something in the form ix for some constant x that the sum can be calculated using a polynomial where the largest term involves nx+1. HINT #1 Phin - phin (2) Determine whether Fib(n) = --------------- sqrt(5) 1+sqrt(5) 1-sqrt(5) given Phi = --------- and phi = --------- 2 2 using induction. Clearly state the inductive hypothesis, what you will prove in the inductive step, and the show the details of that proof. Remember, the 0th Fib number is 0 and the 1st is 1. HINT #2 HINT #3
