Recent Tutoring Session Reviews
"During my session with the student, we covered trigonometric functions, and focused mainly on how to derive the exact values of the cosine and sine of certain angles using the unit circle. He is a very fast learner, and grasps the concepts extremely fast. He is eager to learn, and always asks questions which show how curious he is about the material."
"Went through various aspects of matrices and linear equations: solving for a system of equations with Gaussian elimination, 3x3 inverse matrices, finding the area of a triangle and polygons, determining the equation of a polynomial, deriving the velocity of a wheel, and others."
"Reviewed previous problems involving finding intercepts, finding inverses, and using the quadratic formula. I suggested graphing equations even if the question did not require it so that he could verify he did not miss a negative sign or other simple errors."
"We covered the following topics: using reference angles to compute the sine, cosine, etc., of angles outside the first quadrant; evaluating basic inverse trig functions; using right triangles with inverse trig functions; and solving trig equations. She excelled at most of these topics on the first try. We focused on solving trig equations using quadratic methods, and I showed her a substitution method that she took to very well. I plan to show her how to check herself so that she can prevent committing errors on tests. Great first session."
"This session we spent our time reviewing a quiz that the student got to take home, learning the law of sines, the law of cosines and practicing linear combinations. The quiz covered material that we have covered in previous sessions, such as inverse trig calculations, linear combinations and the double angle formula. After we reviewed the quiz we covered some new material: the law of sines and the law of cosines. Namely how these two laws are used to calculate the area and perimeter of triangles that aren't right triangles. We worked some practice problems and examined how the law of cosines is Pythagorean in nature."
"Lesson 80: We covered trigonometric Identities. The student wanted to know how to remember the rules for trigonometric identities. Lesson 84: I explained factorable trigonometric expressions and sketching sinusoids. The student faced some minor procedural mistakes. Lesson 85: We discussed advanced trigonometric equations and clock problems. The student has some procedural doubts. Lesson 88: We covered exponential functions. Lesson 89: We covered geometric progression. The student mentioned that she did well on her unit test that she took last Wednesday. She is still waiting on getting her results."
