Solving some HW04 problems in class

I will solve some HW04 problems in class on Tuesday. These will be some of the problems which will not be graded. I will also stay a bit longer in the classroom after the Tuesday lecture to answer more HW04 related questions.

Comment on HW04

In HW04, Problem2, Vo represents the output voltage, i.e., voltage with respect to the ground at the output node.
