Today Complex Number Revision was discussed Re: Website Resources, Notes Handout and looking at the 'Binomial Theorem' tomorrow in preparation for Friday.
We then looked at an example from HW finding the equations of tangents to a given circle from a given point outside the circle. The final example in 4.4 Tangents relating to Pythagoras' Theorem (as below) was demonstrated.
Quickly at the end of class we looked at the examples in 4.5 Chords of circles.
HW: Look at some questions relating to the Chords in Ex. 4.5
