• Have looked at how numbers are represented computationally(bits, binary, floating point) and a sample of Mathematica. We will move onto to pre-calculus next week. Before we do this though, a recap on Mathematica.
• Tutorial questions:
  1. What is the sum 1+4+7+¼+301 equal to?
  2. What do we get if we integrate xsinx and then differentiate?
  3. Find the roots of x⁴-3x³+2x²+x+8 = 0. Plot it too, what is the relationship between this and the roots?
  4. What is (361)₈ in binary? and in base 10?
  5. Express 22/3 in binary.

• The page is not complete yet, but will be by the end of the week.
• Remember if have a problem to sort it out at the end of the class. In general I prefer to end earlier to have more time to answer questions afterwards.
