1. (5 points)

Finding a re-arrangement of the equation

exp(*x*)−3*x*−1=0

which will converge to a solution in the interval (1,3) to four decimal places when the fixed point iteration method is used.

2. (10 points)

Finding the root of the equation

*x*tan(*x*) = 2

in the interval (0,π/2) using (i) Bisection method; (ii) Secant method.

3. (5 points)

The design of a car suspension system involves a trade-off between comfort and stability for all driving conditions and speeds. Vibration analysis based on proper modeling of a car and required performance upon hitting a pothole reached the following equation:

cos

⎛⎜⎜⎝0.05 *mk *− 4*cm*^{2}_{2 }⎞⎠⎟⎟+ 4*kmc*−*c*2 sin⎝⎛⎜⎜0.05 *mk *− 4*cm*^{2}2 ⎟⎟⎠⎞= 0

where the mass of the car *m* = 1.2 × 10^{3} kg and the damping coefficient of its shock system is *c* = 1 × 10^{4} kg/s.
Find an appropriate value of *k* that satisfies this condition.
