Extracted text: A military radar identified an unknown object flying above Andaman Sea. The Radar Intercept Officer (RIO) justified that this unknown flying object follows a motion equation, s(t)= sin t + 6t° where s in meter and t in second. Justify whether 3-point central difference has higher accuracy in approximating the velocity of the unknown flying object at 15+A second, comparing to 2-point forward difference and 2-point backward difference. Use small increment, h = 10*.
