Document Summary

Math 124, section c, fall 2017, solutions to midterm i (a) lim h 2 f (h) = f (2) = 8 (c) lim h 0+ f ( 2 + h) 4 h. = 1 (e) x = 5, 2 (g) (b) lim h 0 f (6 + h) f (6) h. At t = 0, it is at the point (10, 0). (a) x = 10 cos(t), y = 10 sin(t) (b) the equations have to be of the form x = a + bt, y = c + dt. The horizontal and linear velocities have to match, as stated in the question: = x (t) = 10 sin(cid:18) 11 d = y (t) = 10 cos(cid:18) 11 . The position of the particle at t = 11 /4 is. = 5 2 so a = 5 2( 11 a + 5 2(cid:18) 11 .
