Recent Tutoring Session Reviews
"We found the unit vector formula and imaginary polar coordinate formula. I explained to the student when they will be applied. We also covered systems of equations using the substitution and elimination methods. We also found the augmented matrix from the system given with 2 or 3 variables. We solved for matrices with 2 variables by the Gaussian elimination method."
"We had a very, very solid session today. We carried on with the logarithmic function and its properties. Some problems required the student to use function transformations, a concept learned in a previous chapter. It was really good to see him use function transformations to solve the homework problems. That showed me that he not only understands the current material, but that he can also use previous material as a building block for another concept. He's asked me many times about the point of learning this or that concept, and today he noticed. Overall, this was a very solid session."
"We had our first meeting today. We talked about properties of logarithms and exponentials. My first impression is that the student is smart and is working on some pretty challenging material. As usual, I left him several pages of notes to study from."
"We had the session this morning to finish going over a practice test covering using inverse trig functions to find unknown angles. We covered law of sines at the end of the session as well."
"We looked at a few problems that the student had worked on, and then we focused on graphing sinusoidal functions. Starting with defining what that means, and then we went through the possible transformations, strategies, and details to include."
"We looked at the previous week's identities in a different way. We went over calculating the exact values of trigonometric functions using angle sum and difference formulas for an upcoming exam. We looked at calculating exact values for trig functions of angles in the four quadrants by using right-triangles plotted on the Cartesian coordinates and substituting the values for the opposite and adjacent sides in appropriate expressions. Issues with algebra remain, but manipulations are coming more easily."
