Lembaran kerja Had dengan jawapan
1.Mudah
f(x) = (x2 − 4x − 5)/(x + 1)x → −1
L =
2.Mudah
Cari had L = limx→1 (√x − 1)/(x − 1).
f(x) = (√x − 1)/(x − 1)x → 1
L =
3.Sederhana
Cari had L = limx→∞ (1 + 1/x)3x. Berikan nilai perpuluhan.
f(x) = (1 + 1/x)3xx → ∞
L =
4.Sederhana
Cari had L = limx→∞ (√(9x2 − 4x) − 3x).
