Read this First
A little known fact – your fx-991ES PLUS or fx-115ES
PLUS calculator has some very powerful features for
performing complex number calculations. This ebook
is a companion to Matrices and Complex Numbers
published by Cambridge Paperbacks.
Working through this ebook you will encounter
problems that would be very difficult to solve
manually. However with the use of your fx calculator,
you will soon realise how powerful it is in performing
really difficult calculations.
Complex numbers are based on = √−1 and when
you start using your fx calculator in its complex
number mode you will see the real and imaginary
numbers in the display.
As in the other ebooks in this series, you are
encouraged to work through each example with your
own fx calculator. This active learning will enhance
your understanding of complex numbers and build
your mathematical knowledge.
