Algebra (Metric)

Class Details

Tom Baker

This class covers the definition of the derivative from first principles, differentiation of key functions sums, products, quotients and composites, and using differentiation to sketch curves and solve problems. If you've done A-level Maths, this is mostly a revision module.

Quadratics

This unit covers topics at Higher GCSE / beginning of A-level; Science and Engineering courses at Imperial will assume you know them. This unit introduces topics such as factorising quadratics, completing the square, using the quadratic formula, solving quadratic equations.

Rational Expressions

Simplifying rational expressions, partial fractions, polynomial division, graphs of rational functions. This is an A-level topic; Science and Engineering courses at Imperial will assume you know it.

A rational expression is one polynomial divided by another; simplifying sums of rational expressions by putting them over a common denominator.

Lesson Not yet graded

Resolving rational expressions into partial fractions. (You meet simple cases at A-level, and more complicated ones in Further Mathematics.)

Lesson Not yet graded

What happens if the degree of the numerator is greater than than of the denominator?

Lesson Not yet graded

Sketching graphs of rational functions.

Lesson Not yet graded

Series

Arithmetic and geometric sequences and series (this is an A-level topic, and Science and Engineering courses at Imperial will assue you know it). Convergence of series (this is a university level topic, which you'll meet in a First Year course).
