1.Easy
xy25x = 25

Find the limit L = limx→25 (√x − 5)/(x − 25).

f(x) = (√x − 5)/(x − 25)x → 25
L =
2.Easy
xy1x = 1

Find the limit L = limx→1 (√x − 1)/(x − 1).

f(x) = (√x − 1)/(x − 1)x → 1
L =
3.Medium
xyy = L

Find the limit L = limx→∞ (1 − 2/x)3x. Give a decimal value.

f(x) = (1 − 2/x)3xx → ∞
L =
4.Medium
xyy = L

Find the limit L = limx→∞ (2x3 + 2x + 7)/(2x3 + 5x + 6).

f(x) = (2x3 + 2x + 7)/(2x3 + 5x + 6)x → ∞
L =
5.Hard
xyx = 0

Find the limit L = limx→0 (1 − cos 3x)/(x²), with x in radians.

f(x) = (1 − cos 3x)/(x²)x → 0
L =
6.Hard
xyx = 0

Find the limit L = limx→0 ln(1 + 3x)/sin(x), with x in radians.

f(x) = ln(1 + 3x)/sin(x)x → 0
L =
