The a t
(calc-taylor) [taylor] command computes
a power series expansion or Taylor series of a function. You
specify the variable and the desired number of terms. You may
give an expression of the form ‘var
= a’ or
‘var -
a’ instead of just a variable to produce
a Taylor expansion about the point a. You may specify
the number of terms with a numeric prefix argument; otherwise the
command will prompt you for the number of terms. Note that many
series expansions have coefficients of zero for some terms, so
you may appear to get fewer terms than you asked for.
If the a i command is unable to find a symbolic integral for a function, you can get an approximation by integrating the function's Taylor series.
