A military radar identified an unknown object flying above the Andaman sea. The
Radar Intercept Officer (RIO) justified that this unknown flying object follows a
motion equation, s(t)= sint +603 wheres s in meter and in second.
Analyze whether the 3-point central difference has higher accuracy in approximating
the velocity of the unknown flying object at 22 second, comparing to 2-point forward
difference and 2-point backward difference. Use small increment, h-103

To identify how much heat is required to bring a kettle of water to its boiling point,
you are required to calculate the specific heat of water at 61°C. The specific heat of
water is given as a function of time in Table Q1(a).

(i) Determine the specific heat value at T-61 °C using a Second order Langrange
polynomial.
(ii) Determine the specific heat value at T-61 °C using a Third order Langrange
polynomial.
(iii) Determine the absolute relative approximate error, leal obtained between the
results from the second order with the third order polynomial.
