Please finish these exercises from section 1.3 (1, 2, 3, 6, 7, 8). On number 7, you are asked to use a result obtained from number 5. The answer to number 5 is: 16x^2+25y^2=400. Use this result to complete number 7.
Update: #6 will be the only presentation problem for Monday.
On Monday we will have a catch-up and summary day. We'll also finish the remaining exercises from 1.3.
