An applet to look at Taylor polynomial approximation of a function
f(x). The function is in black, the Taylor polynomial is in
green, and the error is in red.
The values of x_0, x_1, and n are controlled either by using the
sliders in the window or by entering values in the boxes and hitting
the set value button. The formula for f(x) can be changed ether by
entering a value in the box or by right-clicking (command-clicking
for Mac users)
on the function and choosing edit.
