Passionate School Science tutor excelling in engaging learning with attention to need based study approach.

The Student and Tutor reviewed tangent line and linear approximations, practicing calculations for various functions and exploring the concept of limits as they relate to derivatives. They also touched upon the summation of series, binomial expansions, and the foundational principles of calculus, including integration. The session concluded with a discussion on how mathematical equations are formed and discovered.

The tutor and student reviewed fundamental concepts in pre-calculus, specifically trigonometry. They covered definitions of trigonometric functions, the relationship between degrees and radians, and the concept of periodicity. The student practiced solving basic trigonometric equations with the guidance of the tutor, and future sessions will focus on graphical representations and calculator-based problem-solving.

The Student reviewed trigonometric functions, radian angle measurements, and the graphs of sine, cosine, and tangent. The Student practiced identifying key features of the trigonometric graphs. The session ended with plans to continue exploring trigonometry in the next lesson.

S Sahai assisted a student from the University of California, Los Angeles, with a transshipment problem. The lesson focused on setting up the problem in Excel and using the solver function to minimize transportation costs. They defined variables, constraints, and the objective function, and also discussed why the solver naturally produces integer solutions. The learner will work on question three in a future lesson.

S Sahai guided Harshita through a practical application of business analytics, specifically tackling a transportation problem. The lesson centered on structuring the problem within Excel and employing Solver to optimize and minimize transportation costs. Together, they established definitions for inflow, outflow, balance, and constraints, and calculated total costs using SUMPRODUCT. Harshita will finalize the problem setup and solution, which S Sahai will review in their subsequent lesson.

S Sahai tutored a student from Brentwood on using Excel's solver function to determine coefficients for linear and quadratic regression models. The learner worked on minimizing the sum of squared differences to find optimal values for B0 and B1 in both linear and quadratic equations. They plan to cover the next question, which involves constraints, in their next lesson on Tuesday.
