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

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada

the answer should be in the picture.
