Recent Tutoring Session Reviews
"Today, we prepared for the student's exam tomorrow. The exam covers chapter 6,7,8, and 9. We were able to cover many problems for each chapter. She has a good understanding of the material, so I'm not worried about her performance. As long as we get to review the problems for homework twice or at least once, she will grasp the material."
"We worked on packet over charges and Coulomb's law, then discussed similarities between calculations of gravitational force and electric force and when each is dominant. We worked some Coulomb's law problems involving more than two charges. We also worked on math, converting systems of equations to matrices and solving them."
"Reviewed several of the concepts discussed previously on the physics of electricity and electric circuits. Expanded our discussion of RLC circuits into more detailed analysis of what happens when such circuits are placed in AC current, and reviewed the reason why we use both inductors and capacitors in AC circuits (and not just one). Practiced reactance and impedance problems using a suggested homework problem set. Introduced the concept of a phaser - the vector representation of the difference between current and voltage phases in an AC circuit resulting from the presence of inductors and capacitors, which have imaginary impedances, but very real effects on circuitry."
"In this tutoring session, we went over another homework set. This focused mainly on energy from electric charges and electric potential energy fields, but it moved into how capacitors work for the last portion."
"The student and I continued to review and discuss trigonometry. We reviewed the problems I assigned her for homework that covered terminal angles, reference angles, converting from radians to degrees and vice versa. We talked about inverse trigonometric functions. Then we moved on to talk about the unit circle, we discussed the numbering of the quadrants, and the angles in each quadrant that have reference angles of 30, 45, 60. We reviewed that the x value of a coordinate point on the unit circle is the cosine of the angle and the y value is the sine of the angle. We started to discuss the graphs of sine and cosine functions. I left her with practice problems to do that used the unit circle."
"The student and I covered material on capacitors and the electric field of objects with uniform charge. She was struggling at first with some of the calculus needed to calculate the electric field or potential due to a uniform charge, but she was able to take a step back and understand some of the underlying topics. I included some strategies for what to look for in the problem and how to proceed with simplification and analysis. Her final exam is on Thursday, so we will meet again once more for a final review."
