Question #1884

For the given functions f(x), let x0 = 0, x1 = 0.6, and x2 = 0.9. Construct

interpolation polynomials of degree at most one and at most two to approximate

f(0.45), and find the absolute error.

1. f(x) = cos x

2. f(x) = sqaureroot(1 + x)

3. f(x) = ln(x + 1)

You should write an .m file which computes the Lagrange multipliers, and use it

in your main .m file which approximates the function values.

To Be Handed In: You should hand in all of your (original) code, the approximated

value, and the error. It would be nice if the results were presented

coherently. By that I mean do not just directly copy and paste the command

window, but create a proper presentation of results.
