P1.
Write the Taylor series for f(x) = cos
x about x = 0.
State the Taylor polynomials T2(x),
T4(x), and T6(x) (note that
T3(x)
will be the same as T2(x), and
T5(x) will be the same as
T4(x)).
Plot f(x), T2(x), T4(x), and T6(x), together on one graph,
using demos
or similar (cut-and-paste or reproduce
below).
