Bab Limit
Matematika SMA Kelas XI

1] lim ((6x⁵ - 4x) / (2x² + x))
   x→∞
= lim ((6x⁵/x⁵ - 4x/x⁵) / (2x²/x⁵ + x/x⁵))
  x→∞
= lim (6 - 4/∞⁴) / (2/∞³ + 1/∞⁴)
  x→∞
= (6 - 0) / (0 + 0)
= 6 / 0
= ∞

2] lim (√(4x² + 7x + 1) - √(4x² - 4x + 1))
   x→∞
a = 4; b = 7; c = 1; p = 4; q = -4; r = 1
karena a = p = 4, maka

(b - q) / (2 √a)
= (7 - (-4)) / (2 √4)
= 11 / (2 . 2)
= 11/4
