Recent Tutoring Session Reviews
"We worked on proving trigonometric identities and solving trigonometric functions by using the identities for adding and subtracting angles."
"During my session with the student, we worked on evaluating trigonometric functions without a calculator. She was first having trouble getting started on some of them, however, after working through a few examples, she remembered the method and started solving them by herself."
"- Short review of previous work. + Answer questions on previous work. + Confirm previous work. - Converting large angles to an equivalent unit circle angle. - Basics of graphing sinx and cosx. + Amplitude. + Period. - Answered questions over whole"
"The student's math class was starting its foray into trigonometry, specifically an introduction into basic trigonometric functions (sine, cosine, tangent, secant, cosecant, cotangent). He had a tough time understanding what exactly these functions were and how they were similar and different from previous mathematical operations like addition, multiplication, or square roots. Once I was able to explain them in terms with which he was more familiar, he was quick to learn how to use them in conjunction with angles and the lengths of the sides of right triangles to solve basic trig problems. Most of the sessions was committed to an explanation of this and solving homework for practice and to prepare for any surprise quizzes that his teacher might spring on him in class."
"We reviewed recent material in preparation for his test next week: domains, ranges, composed functions, graphs, transforms, and worked with absolute values for the first time. The student remembered most of the general ideas."
"We went over a couple of problems dealing with bearings and directions. The student knew the concepts and needed some practice thinking through the questions. He was able to demonstrate his understanding of the word problems by drawing out the diagrams. We talked through the steps to find the distance/ time and direction to solve the problems using simple trig functions (sin/ cos/ tan). He has the knowledge and capabilities to solve the problems if he thinks about the given information and what information he can gain to solve the problem."
