Multiple choice questions. Question 1 Suppose that y is a function of a and y = -3 when r = 1. Assume further that dy =1 = -2. If h is close enough to 0, then the approximate value of y when a = 1 + h is (a) -3+h (b) -3+ 2h (c) -3 - 2h (d) -3 - h (e) none of these Question 2 tan(2x) lim (a) 2 (b) 1/2 (c) 0 (d) o (e) none of these Question 3 lim x(3x - V9r- + 1) = T-+-00 (a) 1 (b) -1 ( c) co (d) -oo (e) none of these Question 4 Suppose that re" + yet = r + y, then dy = (a) 1-ely-e (b) 1-ev -ze" ey -1 (c) 1-ex -Ie# (d) ed-1 ex - 1 1-re-ed (e) none of these Question 5 Let y = (sinx)". Then W = (a) In(sin x) + cot r (b) In(sinr) + rcscr (c) In(sin a) (d) In(sina) + r cote (e) none of these
