Recent Tutoring Session Reviews
"In this session we reviewed for the student's upcoming exam. The review packet we worked on was on vectors, conics, Pascal's triangle, binomial theorem, series and sequences. During my time with her we were only able to cover the problems on vectors and conics. She did a great job remembering how to solve problems with vectors. She was struggling a little with writing the formulas for conics, so I had her draw what was given to her so she could use her visualization to figure out the missing variables. This did help her, since she is a visual learner."
"We practiced finding the values of the six trigonometric functions for specific angles using the unit circle. We also went through what negative angles mean and what angles greater than 360 degrees mean. In addition to practicing with the unit circle, we went through other methods of determining the values of the trig functions by drawing a triangle from a point on a graph, finding the sides of a triangle given the sine and cosine of one of its angles, and re-writing 4 of the trig functions in terms of sine and cosine. The student is doing well converting between degrees and radians as well as finding sine and cosine of an angle using a right triangle. Once we covered some of the concepts that were missed in class, the student was much more comfortable finding the values of all six trig functions and relating the unit circle to a specific problem."
"Today we worked on 2 topics in the student's pre-calc class that were giving her some issues. The first were polar coordinates. She understood how to plot polar coordinates but was unsure how to find polar pairs. She quickly grew more comfortable with this type of problem. The other topic that gave her some trouble was parametric equations. These tend to be confusing because we are introducing another variable, t, that both x and y are dependent on. Similar to the polar pairs, she became more comfortable with parametric equations as we talked about them/worked through problems."
"In our session, we covered transformations of continuous and exponential functions as well as simplifying complex problems that required using exponents of the same base. We also reviewed the concepts that she'll see on an upcoming quiz."
"This was a good session. We discussed inverse equations. We wrote, graphed, and found domains and ranges for inverses of functions. Given a linear, quadratic, cubic, or exponential function, we solved for the inverse function and then proceeded with the desired applications to solve for desired parameters."
"1) We covered intrinsic functions and their rules, applying those rules. 2) The student had an issue applying the given formulas and substituting them in. She also had some issues with some algebra as well. 3) We tried substituting the intrinsic functions for just generic variables; that made it easier for her to see the algebra. 4) I told her to go over some of her problems and get familiar with the unit circle; that will help her with some of her calculations."
