Problem 1: Numerical Differentiation (Forward / Central / Backward) An airplane is being tracked by a radar, and data is taken every two seconds in polar coordinates and r. t (s) 200 202 204 206 208 210 (rad) 0.75 0.73 0.71 0.68 0.64 0.60 r (m) 5115 5360 5580 5902 6024 6312 Calculate the velocity of the plane as a function of time, where the velocity V is given by: Please compute the derivatives using the most accurate finite-difference based techniques and comment on the choices you made (why you chose to use a certain method at any given point). Please, note that
