AP Calculus 1. The rectangular equation of the curve e parametrically given by x=1+e' and y=1+e' is: (B) y = 2- X X-1 (C) y = 2 X-1 (D) y == 1- X X-1 (A) y=x (E) None of these 2. Find the value(s) of t for which tangents to the parametric curve described by x=t - 3t and y =t - 2t (A) -1 is/are vertical. (B) -1,0,1 (C) -1,1 (D) 0 (E) None of these 3. If x=sin 2t and y =cos- describe a curve parametrically, then d y at t dx is: 2 (A) - 16 225 2 (B) 16 (C) 2 (D) 32 32 (E) None of these 4. A curve in the xy-plane is defined parametrically by x=lnt +3t+1 and y =2t-e. An equation of the line tangent to the curve at t = 0 is: (A) y=- 5x+3 3 5x-1 (B) y=- 3 (C) y =- - 5x - 3 3 5x-3 (D) y = 3 (E) None of these 1 2 5. The asymptotes of the graph of the parametric equations x = and y == are: t-1 (A) x = 1, y = 0 (B) x=-1,y=2 (C) x = -1 only (D) x = 0, y = -1 (E) y = 2 only This study source was downloaded by 100000789812002 from CourseHero.com on 01-19-2023 17:51:14 GMT -06:00
