Today's lesson was short, and was simply a recap of sketching surfaces through different methods. We can use grid lines, which are reminiscent of traces that we used previously, to piece it together piece by piece, or simply find the relationships between the x, y, and z components. We then practiced finding the surface area of a surface we sketched. Finally, we worked on some problems to further grasp our understanding of the subject matter.
One cool program you can use to help you see surfaces can be seen here:

Don't forget to do the UTexas homework assignment! It's just a review of parametric equations and has some old basic problems of finding areas of surfaces. It's due by tomorrow night.
