We started by talking about the Lorentz Force Law which makes many problems with forces and magnetism make more sense in my opinion.
Then looked at a Friday sheet.
Did a problem with complex numbers starting with a fourth order polynomial that had two zeros given. It involved either long division or synthetic division, we used long division.
Another problem had logarithms. e^x and lnx are functions that counteract each other.
The half angle formula was used for another problem.
