Cari had L = limx→25 (√x − 5)/(x − 25).
Lembaran kerja Had dengan jawapan
1.Mudah
f(x) = (√x − 5)/(x − 25)x → 25
L =
2.Mudah
Cari had L = limx→−1 (x4 − 1)/(x + 1).
f(x) = (x4 − 1)/(x + 1)x → −1
L =
3.Sederhana
Cari had L = limx→∞ (1 + 0.5/x)x. Berikan nilai perpuluhan.
f(x) = (1 + 0.5/x)xx → ∞
L =
4.Sederhana
Cari had L = limx→∞ (√(x2 + 5x) − x).
f(x) = √(x2 + 5x) − xx → ∞
L =
5.Sukar
Cari had L = limx→0 (e0.5x − 1 − 0.5x)/x².
f(x) = (e0.5x − 1 − 0.5x)/x²x → 0
L =
6.Sukar
Cari had L = limx→0 (1 − cos 5x)/(4x²), dengan x dalam radian.
f(x) = (1 − cos 5x)/(4x²)x → 0
L =
