2. The position of a water particle flowing in a tube at the Water Treatment Facility is given by the function of time: f(t)=25t³-6t² + 7t-88 Use zero- through third-order Taylor series expansions to predict the position of the water particle at 3 seconds f(3) using a base point at t = 1. Compute the true percent relative error for each approximation.

Expert Solution
Step 1

Taylor's series is used for the expansion of the function. The Taylor's series is,

f(x)=f(a)+(x-a)f'(a)+x-a22!f''(a)+x-a32!f'''(a)+.......

zeroth order is,

f(x)=f(a)

The first order is,

f(x)=f(a)+x-af'(a).

The second order is,

f(x)=fa+x-af'(a)+x-a22!f''(a).

The third order is,

f(x)=fa+x-af'(a)+x-a22!f''(a)+x-a33!f'''(a).
