In the interval 13 < x < 14, the equation

3 + x sin(x/4) = 0, where x is measured in radians,

has exactly one root, α.

(a) Starting with the interval [13, 14], use interval bisection twice to find an interval of width 0.25 which contains α.

(b) Use linear interpolation once on the interval [13, 14] to find an approximate value for α.
