increment h. The list returned as the first output object includes the following
items:
1 - Bi-directional limit of the function at point of expansion, i.e.,
2 - An equivalent value of the function near x = a
3 - Expression for the Taylor polynomial
4 - Order of the residual or remainder
Because of the relatively large amount of output, this function is easier to handle
in RPN mode. For example:
Drop the contents of stack level 1 by pressing ƒ, and then enter μ, to
decompose the list. The results are as follows:
In the right-hand side figure above, we are using the line editor to see the series
expansion in detail.
