Applications of sequences and series |
2007-08-27 |
|
From Trish:
I'm a grade 12 learner working on a math project based on sequences and series. I'd like to know the different types of sequences and series such as fibonacci, fourier, farey, etc.
I've already used the Fibonacci Sequence and Harmonic Series
and need two more.
The simpler the sequence or series type the better.
I'd also like to know in which non-mathematical areas use sequences and series
and how.
Areas such as engineering or science.
