1. The velocity of a rocket is given by v(t) = 2000 In
-9.8t, 0≤t≤30 where
14×10¹ - 2100t
v is given in m/s and t is given in seconds. At t=16 s and using At= 2 s,
a. Use forward difference, backward difference and central difference
approximations of the first derivative of v(t) to determine the acceleration of the
rocket.
b. If the true value of the acceleration at t=16 s is 29.674 m/s², calculate the absolute
relative true error for each approximation obtained. What can you conclude from
these values of the relative errors?
2. Determine the second derivative of f(x)=x²e²* at x = -2 with a step-size of h=0.50 using
Central difference approach.
