Recent Tutoring Session Reviews
"We had a review session on "Vectors and Operations on Vectors." We determined the sum and difference of two and more vectors geometrically and graphically, using the rule of triangle or rule of parallelogram. Also, we calculated the magnitude and direction for the vector given by the coordinates of its ends or its own coordinates. Furthermore we were justifying if vectors are orthogonal using the scalar product."
"We covered radians-degrees conversion, complementary and supplementary angles, and coterminal angles. We also covered arc length and circumference. I told the student things to remember: radians and degrees are both units that measure angles; centimeters, inches and feet, on the other hand, are units that measure distance; circumference (the "distance" or "length" of the outside of a circle (the amount of crust on the outside of a pizza, for example) is measured in inches, cm, feet, or some unit of distance; circumference = 2 * pi * radius; and arclength, similarly, measures a part (or an arc) of the circumference. For example, the arclength could be 2 pizza crusts. I reminded her that the ratio of arclength to circumference with be equal to the measure of the central angle to the total angle of a circle (360 degrees or 2 pi radians) and therefore, arclength/circumference) = (central angle in degrees /360) or (central angle in radians/2pi). I look forward to seeing her on Thursday!"
"Today we worked through review problems from Chapter 5, in preparation for the upcoming test on Wednesday and Thursday."
"The student and I went over homework problems involving finding the six trigonometric values of an angle. By the end of the session, the student was able to solve the problems correctly."
"During this session, the student and I worked on identifying the graphs of the six trigonometric functions via an online quiz. The graph recognition activity included horizontal and vertical transformations."
"Today we reviewed more trigonometric functions, specifically graphing and translating graphs for amplitude, period, and phase. We set a series of rules to follow for these types of problems."
