We start this chapter with a general introduction to sequences and series. Sequences and series are of great interest because a computer or calculator uses series internally to calculate many functions, such as the sine of an angle, the logarithm of a number, and so on. We then cover some specific sequences, such as the arithmetic progression and the geometric progression. Progressions are used to describe such things as the sequence of heights reached by a swinging pendulum on subsequent swings or the monthly balance on a savings account that is growing with compound interest.
We finish this chapter with an introduction to the binomial theorem. The binomial theorem enables us to expand a binomial, such as (3x2 − 2y)5, without actually having to multiply the ...
