*** For the second midterm, the average was 73 and the median was 78.
*** If you would like to calculate your (rough) preliminary grade in this course here's how.
1) Compute your homework score: (hw1+hw2+hw3+hw4+hw5)/184*25 and add 25 for your webwork (this is out of 50);
2) compute your exam score: exam1*2 + exam2/74*200 (this is out of 400);
3) add 1) and 2), divide by 4.5 (this is out of 100);
4) roughly: 85-100 is an A, 70-84 is a B, 60-69 is a C, 59 and below is a D.

Section 3.1: 12, 14, 18 (see maple notes below for 12 and 14) You will have to use Maple for some ofthis homework. Here's how to get started:
1) Maple can be downloaded from here . With Maple available:
2)Open maple. Load the plots package using the command with(plots); (note the semicolon). Maple will respond with a list of commands available with this package.
3)Use the help facility to read about the spacecurve command. Try spacecurve([t*cos(t),t*sin(t),t], t=-20..20, thickness=2,numpoints=1000); and experiment with different thicknesses and numpoints and values of t. Click on the graph and move the mouse to view the graph from different perspectives.
4)Use the help to find out about plot3d to get a graph of z=\sqrt(x^2+y^2); note this is half of the surface z^2=x^2+y^2.
Section 3.1: 12, 14 (attach your maple output for both - be sure to clean up your failed attempts and only hand in relevant output).
Section 3.2: 7 (Use maple help to find out about parametric plots. Use maple to graph the curve of question 7 (take a=2). Note the symmetries of the graph. Then do the rest of the question.)
Section 2.2: 10, 13, 42
Section 2.3: 20 (find the gradient as well), 24, 26, 30, 37 (use the derivative at (1,2,2)).
Section 1.2: 16 (both the parametric and the cartesian equation)
Section 1.4: 24
Section 1.5: 14
Section 2.1: 12, 8
Section 2.3: 18, 38 (take n=2)
