Argument question?

The argument can be written as any angle that would rotate the positive sense of the x-axis onto the complex number in question. 
For example:
  • 270 degrees is the same as -90 degrees
  • 180 degrees is the same as -180 degrees
  • or pi radians is the same as - pi radians

You could have started the above question by first dividing in Cartesian form by multiplying above and below by the conjugate of the denominator and then converting your answer into Polar form. 

The video (right) which is a solution to the question asked on the Christmas exam, outlines many of the skills and knowledge required in this area.

Today a number of students were absent due to a German thingy.

We looked over HW 7.6 Q.7 discussing how it may be possible to come up with the formula for Tn by observation. We decided that their was a flaw in Q.7 b in that the solution doesn't work for T1.

We then looked over Sigma notation questions in section 7.5

(class notes will be added tomorrow)

HW: Look over this chapter and identify any areas that need further explanation.
