1.Easy
xyx = −4

Find the limit L = limx→−4 (x2 − 16)/(x + 4).

f(x) = (x2 − 16)/(x + 4)x → −4
L =
2.Easy
xy36x = 36

Find the limit L = limx→36 (√x − 6)/(x − 36).

f(x) = (√x − 6)/(x − 36)x → 36
L =
3.Medium
xyy = L

Find the limit L = limx→∞ (1 − 1/x)3x. Give a decimal value.

f(x) = (1 − 1/x)3xx → ∞
L =
4.Medium
xyy = L

Find the limit L = limx→∞ (√(x2 + 2x) − x).

f(x) = √(x2 + 2x) − xx → ∞
L =
5.Hard
xyx = 0

Find the limit L = limx→0 ln(1 + 4x)/sin(2x), with x in radians.

f(x) = ln(1 + 4x)/sin(2x)x → 0
L =
6.Hard
xyx = 0

Find the limit L = limx→0 (1 − cos 5x)/(4x²), with x in radians.

f(x) = (1 − cos 5x)/(4x²)x → 0
L =
