Function TAYLR produces a Taylor series expansion of a function of any
variable x about a point x = a for the order k specified by the user. Thus, the
function has the format TAYLR(f(x-a),x,k). For example,
Function SERIES produces a Taylor polynomial using as arguments the function
f(x) to be expanded, a variable name alone (for Maclaurin's series) or an
expression of the form 'variable = value' indicating the point of expansion of
a Taylor series, and the order of the series to be produced. Function SERIES
returns two output items a list with four items, and an expression for h = x - a,
if the second argument in the function call is 'x=a', i.e., an expression for the
increment h. The list returned as the first output object includes the following
items:
lim
f
(
x
)
1 - Bi-directional limit of the function at point of expansion, i.e.,
x→
a
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:
