10. If [x] is the greatest integer not greater than x, then lim, [x] is NI- (B) 1 (C) nonexistent (D) 0 (E) none of these 11. (With the same notation) lim [x] is (A) 0 (B) 1 (C) 2 (D) 3 (E) none of these tan * is 12. ling x (A) 0 (B) 1 (C) T (D) 0 (E) The limit does not exist. 13. lim sin 2 is (A) 1 (B) 2 (C) (D) 0 (E) x 14. lim sin x (A) is nonexistent (B) is infinity (C) oscillates between -1 and 1 (D) is zero (E) is 1 or -1 sin 3x is 15. life sin 4x (A) 1 (B) (C) AIW (D) 0 (E) nonexistent 16. lim 1 - cos * is (A) nonexistent (B) 1 (C) 2 (D) 20 (E) none of these sin * is 17. lim 2 + 3x (A) 1 (B) W / - (C) 3 (D ) 0 ( E ) A Im 18. lim sin - is (A) (B) 1 (C) nonexistent (D) - 1 (E) none of these 19. lim tan HE is (A) (B) 0 (C) 1 (D) T (E) 0 20. lim x2 sin - X (A) is 1 (B) is 0 (C) is co (D) oscillates between - 1 and 1 (E) is none of these
