The Student and Tutor practiced finding first and second-order partial derivatives for a variety of multivariable functions. They applied differentiation rules such as the product rule, quotient rule, and chain rule to polynomial, exponential, rational, and square root expressions. The session concluded with a plan to review a specific challenging problem involving complex algebraic simplification in the next session.

The Student and Tutor worked through 16 problems involving partial derivatives and critical points for functions of two variables. They practiced calculating derivatives and solving simultaneous equations to find critical points, as well as interpreting maxima, minima, and saddle points from contour plots. The session concluded with a plan to start a new topic after a short break.

Student and Tutor engaged in an exam revision session covering key Mathematics concepts. They practiced finding equations of parallel and perpendicular lines, solved problems related to networks including the Handshaking Lemma and minimum spanning trees, and reviewed time calculations. The session focused on problem-solving techniques and understanding core principles for each topic.

The Student and Tutor practiced solving problems involving partial derivatives to find marginal costs and production rates for multi-variable functions. They then learned the formula for finding the equation of a tangent plane to a surface and applied it to several examples, including identifying errors in a sample solution. The Tutor will send the practice file to the Student.

The Student and Tutor extensively practiced calculating first-order partial derivatives for various multivariable functions. They applied chain, product, and quotient rules to these calculations, interpreted partial derivatives from level curves, and analyzed real-world scenarios. They also discussed plans for an additional hour-long session on Sunday for further practice.

Student and Tutor reviewed key Mathematics concepts including data analysis (mean, median, mode, range, frequency tables, weighted average, interquartile range), budgeting and savings calculations, and linear relationships (y=mx+c). The student practiced solving various problems for each topic. For the next session, the Student requested to review networking trees, and parallel and perpendicular lines.
