Take note of the Exam Coverage:
1. Bracketing Methods
2. Open Methods
3. Multiroot
4. Bairstow Methods (Root of Polynomials)
5. Optimization

Determine the real roots of f(x) = -1 + 5.5x - 4x^2 + 0.5x^3
(a) graphically and
(b) using the Newton-Raphson method to within Es = 0.01%. (use initial guesses x=0, x=2 and x=6)

(5.13)
The velocity v of a falling parachutist is given by

v = (gm/c)( 1-e^[-(c/m)t])

[* read as (gm over c) times the quantity of 1 minus e raise to the negative (c over m) times t]
where g = 9.8 m/s^2. For a parachutist with a drag coefficient c = 15 kg/s, compute the mass m so that the velocity is v = 35m/s at t =9 s. Use false-position method to determine m to a level of Es = 0.1%

(5.14)
Since 5.14 involves an ES 64 word problem on Moments, just solve the problem above (5.13) using the Bisection Method.
