Recent Tutoring Session Reviews
"We worked on arithmetic and geometric series, identifying the type of series, writing formula and calculating nth term and finding sums. The most challenging thing was when series are neither arithmetic or geometric. The student was able to figure out how to write the recursive series and formulas."
"In today's session, we reviewed trigonometric identities and how to use them to simplify expressions. The student completed her assignment on the topic, and she showed great improvement throughout. Then, we completed some reference angles and triangle problems determining the six trigonometric functions given certain relationships."
"We went over sine and cosine graphs and how to modify them. These modifications included changing the amplitude and phase as well as phase shifts and vertical shifts. We also discussed how to find the range of a sine or cosine graph. The student had some trouble with this initially, but eventually figured it out. We also went through some problems involving reference angles and trigonometric functions of various angles. He understands how to do this."
"This was my first session with this student. We spoke about her specific needs with the class and what she hopes to get from out of tutoring. We reviewed with figuring out how to complete word problems involving the law of cosines. We also reviewed how to plot points using polar coordinates."
"We continued to practice working with polar equations and reviewed parametric equations. We practiced solving systems of polar equations by solving for the angle. We went through the different types of polar graphs and determined the equations to generate them. We reviewed how to write a vector equation of a line from two points, a point and a vector, and the rectangular forms. We went through how to convert a parametric equation into rectangular form using various methods, including substitution and using trig identities. The student is doing better working with polar equations, and she was starting to remember working with parametric equations after we started going through some problems."
"We went over direct, joint, and inverse variations, and rational polynomial addition/ subtraction. The student has a test Friday. He understands the concepts."
