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 to look at limits in precalculus
We looked at limits in the context of the last few weeks of precalculus. All of the functions we saw had a (single) removable discontinuity or hole. The limits were found for that point and two other …

Tutoring Conceptual Physics at RLS
We looked at conceptual problems related to magnetism. The book used by the school doesn't use equations much. Which seems like a strange approach to me. I think it would be useful to see something …
Tutoring math at CSUMB, systems of equations and quadratic equations
We started by looking at systems of two equations with two variables and using substitution to solve. Then did a few problems with three equations and three variables. Also used u-substitution to …

Tutoring Precal for RLS, Double angle formulas and graphing trig functions
We started by looking at homework which used the double angle formula. The basic approach was to do two things, could start in either order. 1. Draw the angle with a right triangle on the xy …

Tutoring RLS Precalculus, trig functions and Friday sheet
We looked at some problems with trig functions, especially sum and difference formulas. For many of them, the angle does not need to be known if the sides of the triangle are known. Used the half …
